Biodegradable polymeric nanoparticles based drug delivery systems

A review on the application of inorganic nano-structured materials in the modification of textiles: focus on anti-microbial properties

The idea of electronic yarns and textiles has appeared for quite some time, but their properties often do not meet practical expectations In addition to chemical/mechanical durability and high electrical conductivity, important materials qualifications include weavablity, wearability, light weight, and “smart” functionalities Here we demonstrate a simple process of transforming general commodity cotton threads into intelligent e-textiles using a polyelectrolyte-based coating with carbon nanotubes (CNTs) Efficient charge transport through the network of nanotubes (20 Ω/cm) and the possibility to engineer tunneling junctions make them promising materials for many high-knowledge-content garments Along with integrated humidity sensing, we demonstrate that CNT−cotton threads can be used to detect albumin, the key protein of blood, with high sensitivity and selectivity Notwithstanding future challenges, these proof-of-concept demonstrations provide a direct pathway for the application of these materials as

(Intra)cellular stability of inorganic nanoparticles: effects on cytotoxicity, particle functionality, and biomedical applications.

Effects of Aqueous Exposure to Silver Nanoparticles of Different Sizes in Rainbow Trout

Silver nanoparticles were synthesized and deposited on different types of fabrics using ultrasound irradiation. The structure of silver-fabric composites was studied by physico-chemical methods. The mechanism of the strong adhesion of silver nanoparticles to the fibers is discussed. The excellent antibacterial activity of the Ag-fabric composite against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) cultures was demonstrated.
