Enzymatic degradation of starch-based thermoplastic compounds used in protheses: identification of the degradation products in solution.
Apart from favourable physico-chemical and mechanical properties, the most important requirement for a biodegradable polymer to be used in medical applications is its biocompatibility and the non-cytotoxicity of its degradation products. Their combined effect should assure the safe material degradation under controlled kinetics. The present work analyses the degradation behaviour of blends of c...
متن کاملEnzymatic Degradation of Starch Based Thermoplastic Compounds: Identification of the Degradation Products in Solution
The present work presents the degradation behaviour of blends of corn starch with poly(ethylenevinyl alcohol) copolymer(SEVA-C). The characterization included long term degradation trials on simulated physiological solution with α-amylase up to 200 days, and the degradation solutions were analysed by several techniques. High performance liquid chromatography (HPLC) and colorimetric methods were...
متن کاملElectronic detection of the enzymatic degradation of starch.
[reaction: see text] The enzymatic degradation of starch can be monitored electronically using single-walled carbon nanotubes (SWNTs) as semiconducting probes in field-effect transistors (FETs). Incubation of these devices in aqueous buffer solutions of amyloglucosidase (AMG) results in the removal of the starch from both the silicon surfaces and the side walls of the SWNTs in the FETs, as evid...
متن کاملIn vitro assessment of the enzymatic degradation of several starch based biomaterials.
The susceptibility of starch-based biomaterials to enzymatic degradation by amylolytic enzymes (glucoamylase and alpha-amylase) was investigated by means of incubating the materials with a buffer solution, containing enzymes at different concentrations and combinations, at 37 degrees C for 6 weeks. Two polymeric blends of corn starch with poly(ethylene-vinyl alcohol) copolymer and poly(epsilon-...
متن کاملRetrogradation and Antiplasticization of Thermoplastic Starch
Petrochemical-based plastics are widely used in modern society due to their high effective mechanical and barrier properties (Farris et al., 2009; Siracusa et al., 2008). However, petrochemical-based plastics have become an environmental concern as they are not biodegradable or recyclable. Replacing the petrochemical-based polymers with biopolymers which are renewable has become an attractive i...
