Abstract: Gold nanostars,which have many needle-like nano structures,are synthesized by two-step method and characterized by extinction spectrum and transmission electron microscope.The end of needle like nano structure has a size of 5-10 nm,which can form many Raman hot spots.Gold nanostars are used as the active substrate of surface-enhanced Raman scattering to detect the content of plasticizer dibutyl phthalate (DBP),the detection limit achieves 10 ng.Gold nanostars have a potential application in providing rapid detection of plasticizers in food,daily necessities and other environments.
