Graphene laminated gold bipyramids as sensitive detection platforms for antibiotic molecules.
Atomic layers of graphene were optomechanically laminated onto gold bipyramids (length of ∼95 ± 3 nm and sharp tip radius less than 10 nm) using laser induced shock pressure. The fabricated graphene-gold bipyramid hybrids were employed as surface enhanced Raman scattering (SERS)-active substrates for the detection of tetracycline, an antibiotic, at very low concentrations.
