▎ 摘 要
NOVELTY - A nano-scale bio-composite comprises 0.02 micrograms/ml nano level bio-compound,10 micrograms/ml graphene oxide, a low molecular weight chitosan complex solution and 0.001-10 milligrams/ml recombinant allophycocyanin solution of maltose binding protein tag and histidine tag blend phosphate buffered saline solution. USE - Nano-scale bio-composite for use as biosensor or biochemical marker for detecting blood glucose and monosaccharides content in food and medicine (all claimed). ADVANTAGE - The bio-composite has high specificity and high sensitivity.
