Bare gold nanoparticles selectively enhance the Raman signal of beta-agnonists in swine hair extract at 780 nm, which enables analysis of beta-agonists in swine hair extract without chemical labeling, purification, or separation. The analysis is multiplexable and the LOD of beta-agonists is around ng/mL in the assistance of microfluidic paper.
