It involves engineering with materials that have size dimension in nanometer range. As important biological entities like virus, pores of biological membranes, proteins, etc also share their sizes in the nanometer ranges; there has been an extensive application of nanotechnology in biology and biomedicine. Nanomaterial based drug delivery offers one of the most useful techniques to administer therapeutics in living cells and tissues. Mesoporous silica nanomaterials act as excellent hosts to store and deliver guest molecules. In this book, research topics on the development of mesoporous silica nanomaterials as a stimuli responsive and controlled release delivery agents have been discussed. Magnetic nanoparticles were utilized for targeting the drug delivery assembly to a site of interest and induce stimuli responsive drug release in 'proof of principle' studies. The work described in this book is expected to provide a rational approach towards designing targeted and stimuli responsive smart drug delivery systems.

This book was released on 2019 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multifunctional mesoporous silica nanoparticles (MSNs) have aroused much attention during the past decades for drug delivery and bioimaging applications because of their intrinsic properties including extremely high surface area, large pore volume, tunable pore diameter, easy surface modification, and high biocompatibility. Even though MSNs have these preeminent properties, rendering this unique nanostructure a promising nanocarrier for biomedical applications, several hurdles still challenge the fields of drug delivery and bioimaging when using MSNs as the nanocarries: (i) high loading and high release amounts of water-insoluble drugs delivered to the site of diseases; (ii) precise control of the dosage of drugs delivered to the site of diseases using non-invasive external stimuli; and (iii) construction of MSNs-based shortwave infrared optical imaging contrast agents as an innovative tool for bioimaging and cancer diagnostics. Therefore, this dissertation primarily focuses on the development of innovative strategies that solve these unmet needs and that advance the research in the field of biomedical applications using MSNs as the nanocarriers. In this dissertation, first of all, we review the research work, which mainly focuses on the design and synthesis of multifunctional MSNs and nanomachines for biomedical applications in Accounts of Chemical Research. A wide variety of nanomachines responsive to the different stimuli (pH, redox, enzyme, heat, light, and/or magnetic field) are discussed in this Account. Additionally, we develop a facile strategy for MSNs delivery and release of the water-insoluble drug clofazimine (CFZ), which is used to treat multidrug-resistant tuberculosis. The strategy employs a companion molecule as a chaperone to improve both the loading of CFZ into the pores of MSNs and its subsequent release, thus enabling both high loading and high release of this water-insoluble drug by MSNs. In vitro treatment of macrophages infected with Mycobacterium tuberculosis with the optimized CFZ-loaded MSNs killed the bacteria in the cells in a dose-dependent manner. These studies demonstrate a highly efficient method for loading nanoparticles with water-insoluble drug molecules and the efficacy of the nanoparticles in delivering drugs into eukaryotic cells in aqueous media. Additionally, we used a noninvasive alternating magnetic field (AMF) to stimulate and control the dosage of drug release from MSNs. Noninvasive stimuli-responsive drug delivery using AMF in conjunction with superparamagnetic nanoparticles also offers the potential for the spatial and temporal control of drug release. In vitro studies showed that the death of pancreatic cancer cells treated by drug-loaded nanoparticles was controlled by different lengths of AMF exposure time due to different amounts of drug released from the carriers. Finally, to develop a new shortwave infrared (SWIR) optical imaging contrast agent which has a higher tissue penetration depth, we demonstrate that J-aggregates of near infrared (NIR) fluorophore IR-140 can be prepared inside hollow mesoporous silica nanoparticles (HMSNs) to result in nanomaterials that absorb and emit SWIR light. The use of J-aggregates stabilized in HMSNs as SWIR imaging agents has the potential to overcome the stability, toxicity, and brightness challenges of contrast agents for this compelling region of the electromagnetic spectrum. Collectively, in this dissertation, we explore and develop innovative strategies to load and deliver high amounts of water-insoluble drugs; control the dosage of anticancer drugs released from MSNs triggered by an AMF; and establish a new SWIR optical imaging contrast agent based on the superior carriers - MSNs.

This book was released on 2006 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented and discussed within involves the development of novel biological applications of mesoporous silica nanoparticles (MSN) and an investigation of mesoporous material by transmission electron microscopy (TEM). A series of room-temperature ionic liquid (RTIL) containing mesoporous silica nanoparticle (MSN) materials with various particle morphologies, including spheres, ellipsoids, rods, and tubes, were synthesized. By changing the RTIL template, the pore morphology was tuned from the MCM-41 type of hexagonal mesopores to rotational moiré type of helical channels, and to wormhole-like porous structures. These materials were used as controlled release delivery nanodevices to deliver antibacterial ionic liquids against Escherichia coli K12. The involvement of a specific organosiloxane function group, covalently attached to the exterior of fluorescein doped mesoporous silica nanoparticles (FITC-MSN), on the degree and kinetics of endocytosis in cancer and plant cells was investigated. The kinetics of endocystosis of TEG coated FITC-MSN is significantly quicker than FITC-MSN as determined by flow cytometry experiments. The fluorescence confocal microscopy investigation showed the endocytosis of TEG coated-FITC MSN triethylene glycol grafted fluorescein doped MSN (TEG coated-FITC MSN) into both HeLa cells and Tobacco root protoplasts. Once the synthesis of a controlled-release delivery system based on MCM-41-type mesoporous silica nanorods capped by disulfide bonds with superparamagnetic iron oxide nanparticles was completed. The material was characterized by general methods and the dosage and kinetics of the antioxidant dependent release was measured. Finally, the biological interaction of the material was determined along with TEM measurements. An electron microscopy investigation proved that the pore openings of the MSN were indeed blocked by the Fe3O4 nanoparticles. The biological interaction investigation demonstrated Fe3O4-capped MSN endocytosis into HeLa cells. Not only does the material enter the cells through endocytosis, but it seems that fluorescein was released from the pores, most probably caused by disulfide bond reducing molecules, antioxidants. In addition to endocytosis and release, the Fe3O4-capped MSN propelled the cells across a cuvette upon induction of a magnet force. Finally, an important aspect of materials characterization is transmission electron microscopy. A TEM investigation demonstrated that incorporating different functional groups during the synthesis (co-condensation) changed the particle and pore morphologies.

This book was released on 2020 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation makes contributions to the fields of formulation and delivery of anticancer drugs, antibiotics, and imaging agents, primarily focused on engineering mesoporous silica nanoparticles (MSNs) for stimuli-responsive drug delivery. The strategies and techniques developed in this dissertation will be especially useful for achieving precision medicine or personalized medicine, which is defined as the "right drug, right dosage at right timing to right patient". Although various emerging approaches for personalized disease treatment that take individual variability into account have been developed, the necessity of delivering the desired therapeutics at the desired time to the specific site of the disease and with accurate dosage remains a challenge. Here we first review the previously reported stimuli-responsive MSNs controlled by supramolecular nanomachines for antibiotic and drug delivery. In the second part of the dissertation, we report novel MSNs-based nanoparticles engineered to be responsive to noninvasive stimuli, such as alternating magnetic field (AMF) or high-intensity focused ultrasound (HIFU). AMF-responsive drug delivery demonstrates the controlled therapeutic efficacy for pancreatic cancer cells in vitro by adjusting different lengths of AMF exposure time. The HIFUresponsive MSNs provide a promising platform for magnetic resonance imaging (MRI)-guided HIFU (MRgHIFU)-stimulated cargo delivery. The change of T1 reports on the amount of released cargo which is imageable by MRI ex vivo. Both AMF-and MRgHIFU-stimulation strategies offer the potential for the spatial, temporal, and dosage control of drug delivery. In the last part, we develop an approach to achieve both high loading and high release amount of a water-insoluble antibiotic clofazimine (CFZ) carried by MSNs by using acetophenone (AP) as a chaperone molecule, solving the water insolubility problem faced when treating multidrug-resistant tuberculosis. The treatment of Mycobacterium tuberculosis infected macrophages with optimized CFZ-loaded MSNs shows good therapeutic efficacy in vitro. Finally, we develop a hollow mesoporous silica nanoparticle (HMSN) formulated near infrared (NIR) fluorophore IR-140, to realize a novel biocompatible shortwave infrared (SWIR) optical imaging contrast agent for bioimaging with a higher tissue penetration depth. The J-aggregates of IR-140 stabilized inside HMSNs showed the potential to overcome the stability, toxicity, and brightness challenges faced by common SWIR contrast agents.
