In Vivo Toxicity Study of Gold Composite Nanodevices for use in Imaging and Radiotherapy
Khan M.K., Nair B., Kasturirangan V., Kariapper M.S.T., Nigavekar S.S., Toth K., Rustum Y.M., El-Jawahri A., Bizimungu R., Lesniak W., Balogh L.P., Roswell Park, US
We previously reported on the in vitro toxicity assessment of differently charged dendrimer-gold nanocomposites on normal cells (human endothelial cells) and prostate cancer cells (Khan et al., 2008). In this study we evaluate the in [...]
Imprint Lithography-Based, Multimodal Contrast Agents and the Effect of Shape and Size on Biodistribution
Polymer research and modern medicine are at a critical juncture. Many state of the art, small molecule therapeutics are difficult to deliver effectively because of poor solubility and rapid elimination by the reticuloendothelial system. In [...]
Synthesis and Biopharmaceutical Characterisation of a New Poly hydroxyethyl
A promising approach to improve drug delivery is to modify a polymeric backbone structure by means of copolymerization. Such obtained macromolecular prodrugs (polymer–drug conjugates) may offer many advantages compared to other drug delivery systems: increased [...]
Formulation and Development of Novel Insitu Nasal Gel Containing Glibenclamide Nanoparticles
To provide an alternative route (non-swallowing) and compliance to patient (controlled release), nasal delivery of sulfonylureas is one of the best option among other routes for type II diabetes. Glibenclamide was selected as a model [...]
Diskettes of mucoadhesive polymeric nanoparticles for oral (buccal) transmucosal delivery of Fluoxetine hydrochloride: formulation and characterization
Nanoparticles based mucoadhesive system (diskettes), an alternative novel transmucosal (buccal) delivery of Fluoxetine hydrochloride (antidepressant drug, highly first pass effect) was developed. In this study, the drug was encapsulated into Sodium / Calcium salts of [...]
Modeling of Polymer-Drug Interactions in Biodegradable Tyrosine-Based Nanospheres Using Molecular Dynamics Simulations and Docking
The intensive labor and high cost of developing new vehicles for the delivery of drugs in a controlled manner, highlights the need for a change in their discovery process. Predictive computational models can be used [...]
Paclitaxel-functionalized aspragalan-calcium phosphate nanoparticles
Paclitaxel (PTX) is an important anticancer agent. Its aqueous solubility is very low; hence the available formulation of PTX for clinical use consists of Cremophor EL, which has been associated with several hypersensitivity reactions. In [...]
Process Development and Industrial Manufacturing of Nanotechnology-Based Pharmaceuticals
Process design and development of oral, topical and parentral nanotechnology-based pharmaceuticals are presented. Factors affecting process output and scale-up choices for various dosage forms are discussed with emphasis on critical parameter control and optimization. For [...]
Mechanism of Nitroimidazole Coated Magnetic Nanoparticles Embedded in Micro-organisms as Delivery Systems
Avirulent Bacteria and parasites act as “tiny missile like carriers” capable to carry the magnetic nanoparticles (NMP) together with anticancer or radiosensitizer drugs at the tumor site. We compared the iron-oxide particles binding characteristics with [...]
Newer Methods of Nanoparticle Synthesis: Nitroimidazole properties with Nanometal oxides in Polymer Cages
Nitroimidazoles are radiosensitizers and hypoxia detecting chemosensitizers. Intially nitroimidazoles were single dose antibiotic drugs. Recently, nitroimidazole derivatives have emerged as multifunctional “drug-biomarker monitors” chemical compounds with importance in treatment of tumors, monitoring hypoxia and safer [...]
Microparticles on the Basis of Segmented Polyurethanes for the Treatment of Tuberculosis
The objective of the research is to develop a new drug delivery system based on polyurethane microparticles for the treatment of tuberculosis by pulmonary administration to the lungs. The synthesis and characterization of polyurethane microcapsules [...]
Fashioning of Polymer Multi-functional Nanovector Microparticle Delivery System by High Definition Microextrusion
Gabriele P.D., Hogan A., D’Ottavio J., Flemmens M., Weir M., ARmark Authentication Technologies, LLC, US
Considerable advances have recently been achieved in the development of nano-scale particles for cancer diagnostics and therapies. ARmark Authentication Technologies, LLC has developed a new technology platform to produce stable multifunctional polymeric microcarrier delivery vehicles [...]
Action of Paclitaxel pH-Sensitive Liposomes on B16F1 Melanoma Cells
Long circulating pH-sensitive liposomes loaded with Paclitaxel were developed and characterized for the encapsulation efficiency, release characteristics and its action on B16F1 melanoma cells (low metastatic). Paclitaxel loaded pH-sensitive liposomes showed better release pattern and [...]
Novel Cleavable PEGylated Liposomes for Enzyme Triggerable Release of Nucleic Acid in Tumours
We have developed a dePEGylation approach based on the activity of the proteolytic enzymes that are associated with tumour cells. The elevated enzyme activity facilitates the extravasation of the cells by degrading the extracellular matrix [...]
Chitosan as mucoadhesive agent to enhance absorption of therapeutic proteins encapsulated into solid lipid nanoparticles
Teixeira J., Júlio A., Castro C., Fonseca J., Martins S., Ferreira D., Sarmento B., University of Porto, PT
The aim of this work was to develop Witepsol 85E solid lipid nanoparticles (SLN) containing insulin as biopharmaceutical, and to evaluate their potential for oral insulin administration. The new carrier was coated with chitosan in [...]
Magnetic drug targeting using concept of focused magnet
Jancurova L., Timko M., Bano M., Koneracka M., Repasan M., Kopcansky P., Technical University, Faculty of Electrical Engineering and Informatics in Kosice, SK
Current research on methods to target chemotherapy drugs in the human body includes the investigation of biocompatible magnetic nano-carrier systems, e.g. magnetic liquids such as ferrofluids. The aim of our work was to construct a [...]
