3.2.2. Collagen-based biosensor:
Marine collagen is reported to be non-toxic, environmental friendly, low inflammatory response and biocompatible. There are many reports of marine collagen biomaterial in tissue engineering, though there is a scarcity of data on the marine collagen-based biosensor.
Zong et al. (2006) reported a biosensor using chrome waste from leather waste in a tannery. The collagen grafted biosensor which has been discovered is found to be biocompatible, thermally stable, highly sensitive, and with improved selectivity. Due to the advantages offered by hybrid collagen, zirconia nanoparticles collagen composite was reported to prepare amperometric glucose biosensors.
