Design of SERS nanoprobes for Raman imaging: materials, critical factors and architectures

open access: yesActa Pharmaceutica Sinica B, 2018
Raman imaging yields high specificity and sensitivity when compared to other imaging modalities, mainly due to its fingerprint signature. However, intrinsic Raman signals are weak, thus limiting medical applications of Raman imaging.
