Blatter-Radical-Grafted Mesoporous Silica as Prospective Nanoplatform for Spin Manipulation at Ambient Conditions.

ABSTRACT: Quantum computing and quantum information processing (QC/QIP) crucially depend on the availability of suitable quantum bits (qubits) and methods of their manipulation. Most qubit candidates known to date are not applicable at ambient conditions. Herein, we propose radical-grafted mesoporous silica as a versatile and prospective nanoplatform for spin-based QC/QIP. Extremely stable Blatter-type organic radicals are used, whose electron spin decoherence time is profoundly long even at room temperature (up to T_m ≈2.3 μs), thus allowing efficient spin manipulation by microwave pulses. The mesoporous structure of such composites is nuclear-spin free and provides additional opportunities of embedding guest molecules into the channels. Robustness and tunability of these materials promotes them as highly promising nanoplatforms for future QC/QIP developments.

Evaluation of Mesoporous Silica Nanoparticles as Carriers of Triarylmethyl Radical Spin Probes for EPR Oximetry.

Project description:In vivo measurement and mapping of oxygen levels within the tissues are crucial in understanding the physiopathological processes of numerous diseases, such as cancer, diabetes, or peripheral vascular diseases. Electron paramagnetic resonance (EPR) associated with biocompatible exogenous spin probes, such as Ox071 triarylmethyl (TAM) radical, is becoming the new gold standard for oxygen mapping in preclinical settings. However, these probes do not show tissue selectivity when injected systemically, and they are not cell permeable, reporting oxygen from the extracellular compartment only. Recently, Ox071-loaded mesoporous silica nanoparticles (MSNs) were proposed for intracellular tumor oxygen mapping in both in vitro and in vivo models. However, the EPR spectrum of the Ox071 spin probe is poorly sensitive to mobility due to the small anisotropy of its g-factor and the absence of hyperfine splitting, making it more difficult to study the mobility of the radical inside the MSNs or its location. Using 13C1 isotopologues of Ox071 and the deuterated Finland trityl (dFT) spin probes, which are highly sensitive to molecular tumbling, we showed that the loading of the probes inside homemade and commercial cationic MSNs drastically decreases their mobility while the high local concentration of the probe inside the MSNs leads to dipolar line width broadening (self-relaxation). This decrease in molecular tumbling and line broadening hampers the oxygen-sensing properties of Ox071 or dFT probes used for EPR oximetry when loaded into MSNs.

Mesoporous Silica Nanoparticles as a Potential Nanoplatform: Therapeutic Applications and Considerations.

Project description:With advances in nanotechnology, nanoparticles have come to be regarded as carriers of therapeutic agents and have been widely studied to overcome various diseases in the biomedical field. Among these particles, mesoporous silica nanoparticles (MSNs) have been investigated as potential nanocarriers to deliver drug molecules to various target sites in the body. This review introduces the physicochemical properties of MSNs and synthesis procedures of MSN-based nanoplatforms. Moreover, we focus on updating biomedical applications of MSNs as a carrier of therapeutic or diagnostic cargo and review clinical trials using silica-nanoparticle-based systems. Herein, on the one hand, we pay attention to the pharmaceutical advantages of MSNs, including nanometer particle size, high surface area, and porous structures, thus enabling efficient delivery of high drug-loading content. On the other hand, we look through biosafety and toxicity issues associated with MSN-based platforms. Based on many reports so far, MSNs have been widely applied to construct tissue engineering platforms as well as treat various diseases, including cancer, by surface functionalization or incorporation of stimuli-responsive components. However, even with the advantageous aspects that MSNs possess, there are still considerations, such as optimizing physicochemical properties or dosage regimens, regarding use of MSNs in clinics. Progress in synthesis procedures and scale-up production as well as a thorough investigation into the biosafety of MSNs would enable design of innovative and safe MSN-based platforms in biomedical fields.

Protein sustained release from isobutyramide-grafted stellate mesoporous silica nanoparticles.

Project description:Proteins are great therapeutic candidates as endogenous biomolecules providing a wide range of applications. However, their delivery suffers from some limitations and specifically designed delivery systems having an efficient protein anchoring and delivery strategy are still needed. In this work, we propose to combine large pore stellate mesoporous silica (STMS) with isobutyramide (IBAM), as a "glue" molecule which has been shown promising for immobilization of various biomacromolecules at silica surface. We address here for the first time the ability of such IBAM-modified NPs to sustainably deliver proteins over a prolonged time. In this work, a quantitative loading study of proteins (serum albumin (HSA), peroxidase (HRP), immunoglobulin (IgG) and polylysine (PLL)) on STMS@IBAM is first presented using three complementary detection techniques to ensure precision and avoid protein quantification issues. The results demonstrated a high loading capacity for HSA and HRP (≥ ca. 350 μg.mg-1) but a moderate one for IgG and PLL. After evaluating the physicochemical properties of the loaded particles and their stability over scaling-up and washings, the ability of STMS@IBAM to release proteins over prolonged time was evaluated in equilibrium (static) and flow mimicking (dynamic) conditions and at different temperatures (25, 37, 45 °C). Results show not only the potential of such "glue" functionalized STMS to release proteins in a sustained way, but also the retention of the biological activity of immobilized and released HRP, used as an enzyme model. Finally, an AFM-force spectroscopy study was conducted to decipher the interactions between IBAM and proteins, showing the involvement of different interactions in the adsorption and release processes.

In-depth Endogenous Phosphopeptidomics of Serum with Zirconium (IV)-Grafted Mesoporous Silica Enrichment

Project description:In this study, we developed an approach using Zirconium (IV)-grafted mesoporous beads to enrich phosphopeptides followed by analysis with a high resolution nanoRPLC-MS/MS system. The new method was first tested with tryptic digests of standard phosphoproteins and HeLa cell lysates, with excellent enrichment performance achieved. The method was further used for endogenous phosphopeptidomic analysis of serum samples from pancreatic ductal adenocarcinoma (PDAC) patients and controls. In total, 329 endogenous phosphopeptides (containing 113 high confidence sites) were identified across samples, by far the largest endogenous phosphorylation dataset catalogued to date. In addition, the method was readily applied for phosphoproteomics of the same set of samples, with 172 phosphopeptides identified and significant changes in dozens of phosphopeptides observed. Taken together, this method serves as a benchmark for analyzing serum phosphorylation events. Given the simplicity and robustness of the proposed method, we envision that it can be readily used for comprehensive phosphorylation studies (i.e., simultaneous endogenous phosphopeptidomics and phosphoproteomics) of serum and other biofluid samples.

Indocyanine Green Loaded Modified Mesoporous Silica Nanoparticles as an Effective Photothermal Nanoplatform.

Project description:Photothermal therapy possesses great advantages for the treatment of drug-resistant tumors. Herein, Near Infrared (NIR)-triggered photothermal nanoparticles were developed through loading indocyanine green (ICG), a kind of NIR dye, into amino group-modified silica nanoparticles (SiO2-NH2 NPs). SiO2-NH2 NPs were prepared with immobilization of the amino groups into the framework of silica nanoparticles (SiO2 NPs) by employing (3-aminopropyl)-triethoxysilane (APTES). Before and after the modification of the amino group, the particle sizes of SiO2 NPs showed similar value, around 100 nm. ICG was further adsorbed into SiO2-NH2 NPs by electrostatic attraction to enable SiO2-NH2@ICG NPs as a kind of photothermal agent. The loading rate of ICG to SiO2-NH2 was greatly increased compared to unmodified SiO2, and the stability of ICG was also improved. Moreover, the SiO2-NH2@ICG NPs exhibited efficient photothermal effects due to ICG transforming laser power into local heat through the connected ICG, when NIR laser irradiation turned on for a couple of minutes. Finally, the in vitro antitumor efficacy of SiO2-NH2@ICG NPs was investigated by recording cell proliferation rate and further chronicled the apoptotic morphology evidence by a Calcein-AM/PI fluorescent staining assay, indicating the efficient photothermal targeted therapy for the HepG2 tumor cells.

Near-Infrared Light-Mediated Antibacterial Photodynamic Therapy Based on Erythrosine-Functionalized Mesoporous Silica-Coated Upconversion Nanoplatform.

Project description:Infectious diseases caused by bacteria pose a serious threat to public health, and more worryingly, the unregulated application of antibiotics accelerates the emergence of bacterial resistance, presenting a major challenge to the effective treatment of infectious diseases caused by bacteria. Therefore, there is an urgent necessity to develop efficient and safe antimicrobial systems. Photodynamic therapy (PDT) is an attractive therapeutic approach that does not induce bacterial resistance. However, the clinical application of PDT has been limited by several factors, including the lower tissue penetration depth of photoactivation under visible light irradiation and the uncertain biosafety of photosensitizers (PS). This work presents an near infrared (NIR)-triggered core-shell upconversion nanoparticle-based PDT system composed of mesoporous silica-coated lanthanide-doped upconversion nanoparticles loaded with the photosensitizer erythrosine (UCSE). Upon NIR-triggering, erythrosine generates highly efficient reactive oxygen species that disrupt the cell membranes of Staphylococcus aureus and Escherichia coli, exhibiting a potent photodynamic antimicrobial effect. It is worth noting that the UCSE also exhibits excellent biosafety. In conclusion, we present an efficient NIR-triggered nanoantimicrobial system with excellent antimicrobial capacity and biosafety, which is a new therapeutic strategy for the control of bacterial infectious diseases.

Adhesin Antibody-Grafted Mesoporous Silica Nanoparticles Suppress Immune Escape for Treatment of Fungal Systemic Infection.

Project description:Life-threatening systemic fungal infections caused by Candida albicans are significant contributors to clinical mortality, particularly among cancer patients and immunosuppressed individuals. The evasion of the immune response facilitated by fungal surface components enables fungal pathogens to evade macrophage attacks and to establish successful infections. This study developed a mesoporous silica nanoplatform, i.e., MSNP-EAP1Ab, which is composed of mesoporous silica nanoparticles grafted with the antibody of C. albicans surface adhesin Eap1. The activity of MSNP-EAP1Ab against C. albicans immune escape and infection was then evaluated by using the cell interaction model and the mouse systemic infection model. During interaction between C. albicans cells and macrophages, MSNP-EAP1Ab significantly inhibited fungal immune escape, leading to the enhanced phagocytosis of fungal cells by macrophages, with phagocytosis rates increasing from less than 8% to 14%. Furthermore, after treatment of the C. albicans-infected mice, MSNP-EAP1Ab drastically prolonged the mouse survival time and decreased the kidney fungal burden from >30,0000 CFU/g kidney to <100 CFU/g kidney, indicating the rapid recognition and killing of the pathogens by immune cells. Moreover, MSNP-EAP1Ab attenuated kidney tissue inflammation, with remarkable attenuation of renal immune cell accumulation. This study presents an innovative nanoplatform that targets the C. albicans adhesin, offering a promising approach for combatting systemic fungal infections.
