Chitosan, a natural and abundant biopolymer has been long explored as biocompatible material for the preparation of drug delivery devices. This strategy mostly accomplished using chemically crosslinked chitosan leading to more stable scaffolds. However, crosslinking shown reduce both biocompatibility swelling. In this work was with novel crosslinkers, based on oligo-oxazolines glycidyl methacry...

We show that a new type of hydrogel can be prepared by covalently inter-linking binary blends of microgel (MG) particles and that the swelling ratio and modulus of the gels can be predicted from their composition. In previous work we established that physical gels of glycidyl methacrylate (GMA) functionalised poly(methyl methacrylate-co-methacrylic acid-co-ethyleneglycol dimethacrylate) microge...

Forming a bond to dentin has been a great challenge. Dentin is a vital tissue composed of organic material and water in addition to the inorganic content. Operative procedures on dentin produce a loosely-bound surface of unorganized material known as the "smear layer". For optimum bonding to occur, this layer needs to be removed or altered. A dentin bonding agent should be biocompatible and sho...

The industrialization and urbanization expansion have increased the demand for precious rare earth elements (REEs). In addition, environmental concerns regarding toxic effects of heavy metals on living organisms imposed an urgent need efficient methods their removal from wastewaters aqueous solutions. most technique metal ions is adsorption due to its reversibility high efficiency.
