AI Technical Summary
Existing technologies for antibiotic detection suffer from low efficiency and low accuracy. Traditional SERS substrates are difficult to identify and recycle, resulting in high detection costs and a heavy environmental burden.
The OCC@TiO2@AgNPs composite substrate with a layered structure achieves broad-spectrum and high-sensitivity detection through the semiconductor-plasmotropic synergistic enhancement effect, and utilizes the photocatalytic properties of TiO2 to achieve efficient regeneration and recycling of the substrate.
It enables the detection of multiple antibiotics at the pM level, covering a detection range from 10 pM to 107 pM. It has high detection accuracy, low cost, and is environmentally friendly, making it suitable for aquaculture and food safety monitoring.
