A SERS sensor based on gold nanostars is described. The size and sharpness of the nanostar spikes are tuned to maximize sensitivity and SERS enhancement, yielding a detection limit of 10-15 M and an enhancement factor of 109 . The effectiveness of the sensor is proven for both chemisorbed and physisorbed analytes under non-resonant conditions and its multiplexing capability is demonstrated.
