Alternatively, star polymers (unimolecular, globular, polymer architectures) are an increasingly attractive class of organic nanoparticles for biomedical research purposes. [ 16–18 ] Although topographically similar to dendrimers (i.e., a high local density of polymeric arms, surface functionality, and interstitial regions), they lack the synthetic and structural limitations of dendrimers [ 19 ...
High atomic number molecules, such as gold and platinum, are known to enhance the biological effect of X-irradiation. This study was aimed to determine the radiosensitizing potential of PEGylated nanogel containing gold nanoparticles (GNG) and the cellular mechanism involved. GNG pretreatment increased the levels of reproductive cell death and apoptosis induced by X-irradiation. GNG accumulated...
Nanogels based on poly(N-isopropylacrylamide) are attractive vehicles for prolonged duration local anesthesia because of their tunable size, number of functional groups, thermoresponsiveness and anionic charge. Nerve block durations of up to 9h were achieved using acrylic acid-loaded nanogels loaded with bupivacaine. Increasing the anionic charge density of the nanogels or (for more highly acid...
The characterization of several commercial dextrins and the analysis of the potential of dextrin derived hydrogels for biomedical applications were performed in this work. The structural characterization of dextrins allowed the determination of the polymerization and branching degrees, which ranged from 6 to 17 glucose residues and 2 to 13%, respectively. Tackidex, a medical grade dextrin was c...
