Efficient water soluble nanostructured ZnO grafted O-carboxymethyl chitosan/curcumin-nanocomposite for cancer therapy

Modification of nanostructured ZnO surfaces with curcumin: fluorescence-based sensing for arsenic and improving arsenic removal by ZnO

“…42 Curcumin has also been used to prepare ZnO-curcumin composites. [43][44][45] However, there is no literature work where curcumin is doped on ZnO surfaces. In this work we attempted to prepare a new curcumin doped ZnO nanomaterials, which is termed here as Zn(cur)O, and apply it for developing new uorescence sensing scheme for arsenic as depicted in Scheme 2 and at the same time quick removal of arsenic from water without the oxidation and/or pH treatment.…”

Synthesis and characterization of antibacterial carboxymethyl Chitosan/ZnO nanocomposite hydrogels

“…It is an amphoteric material which shows hydrophilic characteristics [24,25]. Thus CMCh has several advantages over chitosan, such as increased water solubility, better biocompatibility, high moisture retention ability, excellent biodegradability [26], improved antioxidant property [27], as well as, enhanced antibacterial activity [28]. The preparation of O-CMCh is achieved simply by reacting chitosan with monochloroacetic acid in alkaline medium [29].…”

Ex vivo and In vivo Evaluation of Chitosan Coated Nanostructured Lipid Carriers for Ocular Delivery of Acyclovir

“…As corneal epithelial cells bear negative charges, conversion of NLCs to positively charged particles is expected to significantly increase the precorneal residence time of the formulation and subsequently increase corneal penetration [3]. This approach has also been used for other biomedical applications such as transdermal drug delivery as well as encapsulation of DNA and other bioactive substances that require ionic interactions [4][5][6][7][8]. Moreover, in theory, coating of nanoparticles with a natural polymer should further reduce the drug release rate.…”
