使用激光诱导冲击压力将石墨烯的原子层光机械层压到金双锥（长度为~95±3 nm并且尖端半径小于10 nm）上。制备的石墨烯-金双锥杂化材料作为表面增强拉曼散射（Sers）活性基底，用于检测极低浓度的抗生素四环素。
Atomic layers of graphene were optomechanically laminated onto gold bipyramids (length of ~95±3 nm and sharp tips radius is less than 10 nm) using laser induced shock pressure. 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 concentration.
