The main goal of this study was to synthesise and characterise different formulations based on alginate and alginate/chitosan microspheres containing nanoselenium (nano-Se) for controlled delivery applications. Nanosize elemental selenium was produced by using probiotic yogurt bacteria (Lactobacillus casei) in a fermentation procedure. The structural and morphological characterisation of the microspheres...
Herein, the authors developed a new and potential semi-interpenetrating polymer network (semi-IPN) hydrogels of poly vinyl alcohol (PVA), acryl amide and diallyldimethyl ammonium chloride employing chemical cross-linker N, N'-methylene bisacrylamide (NNMBA) and ammonium persulphate as an initiator by radical polymerisation. To analyse the copolymer formation between two monomers and IPN cross-linking...
The research aims to develop a multifunctional system for, implantable biosensing, drug delivery and MRI. Magnetic nanoparticles (MNPs) synthesized by co-precipitation were loaded with sensor and drug into alginate microspheres using a droplet generator. The multifunctional system was characterized using Microscopy, SEM, TEM, XRD, VSM and MRI. MNP had size in the range of 5-15 nm. Biosensor, Diclo,...
Poly(ester-imide)s (PEI)s are a kind of non-vinyl polymers which can be prepared via step-growth polymerization. They contain ester and imide linkages in the polymer backbones and lately show significant applications, such as adhesives, printed circuit boards, membranes, and engineering thermoplastics. Synthesis of chiral polymers is an important field in macromolecular science, they have attracted...
