Introduction * Physical-chemical properties of the -cyanoacrylate * ABSTRACT Currently, new formulations of -cyanoacrylic tissue adhesives, are being studied for the repair of soft and hard tissue in order to improve properties such as: biodegradability, biocompatibility bone flexibility (in the soft tissue applications) and ease of handling. This paper presents a review of scientific literatur...

Porous magnetic supraparticles (p-MSPs) with surface area up to 285.4 m(2) g(-1) have been fabricated by a one-step etching method, which is 4 times greater than the unetched counterpart. They exhibit significantly better biodegradability than their counterpart in both mimicked physiological buffer solution and the cellular environment of HeLa cells.

The chemical synthesis of an aliphatic biopolyester identical to the natural cutin which constitutes the major component of the cuticle of fruits and leaves of higher plants is for the first time achieved and reported. Potential applications of this new material is of great interest because its physical properties, non-toxicity, biodegradability, and availability of raw material.

One of the major environmental threats is the least rate of degradation or non biodegradability of the organic materials under natural condition, e.g. plastics. The plastics of various forms such as nylon, polycarbonate, polyethylene-terephthalate, polyethylene, polypropylene, polystyrene, polytetraflouro ethylene, polyurethane and polyvinyl chloride (Smith, 1964) are being continuously used in...
