nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...

In this study, we analyzed the antimicrobial activities of poly-N-isopropylacrylamide (pNIPAM)-based polymeric nanoparticles encapsulating silver nanoparticles (AgNPs). Three sizes of AgNP-encapsulating pNIPAM- and pNIPAM-NH2-based polymeric nanoparticles were fabricated. Highly stable and uniformly distributed AgNPs were encapsulated within polymeric nanoparticles via in situ reduction of AgNO...

in recent years, utilization of chitosan /tripolyphosphate nanoparticles has been considered greatly as protein delivery vehicles. effects of a variety of factors on final characteristics of nanoparticles have been studied by many investigators. although, the objective of this study was to achieve smaller chitosan nano carriers via changing fabrication parameters such as ph and temperature and ...
