研究目的
Investigating the fluorescent properties of gadolinium-doped zinc oxide nanoporous networks and their application in optical biosensing for detecting biomolecules.
研究成果
Gd-doped ZnO nanoporous networks show promising potential as fluorescent optical sensors for detecting biomacromolecules, with significant fluorescence response at low concentrations. Further research is needed to understand the underlying mechanisms and optimize the doping concentrations.
研究不足
The study did not explore the mechanisms behind the fluorescence ignition at low protein concentrations (10-12 mg/ml) and the optimal doping concentration for maximum fluorescence response.
