Abstract
The disclosure discloses a high-flux and ultra-sensitive detection dot array enhancement chip, and belongs to the field of food safety detection. In the disclosure, single-layer Au nano-particles are chemically bonded onto a hydrophilic substrate, an Au nano-material is naturally deposited in holes of the chip under an electrostatic adsorption action, and a regular dot array is formed. Au particles distributed in the holes are separated with a particle surfactant (CTAB) to form plasma gaps so as to enhance the self-assemble of Au nano-particles distributed on hot-spots for a long range effect, thereby improving the sensing signal in detection efficiency and sensitivity of the chip.
