Interrogating Cells, Tissues, and Live Animals with New Generations of Surface-Enhanced Raman Scattering Probes and Labels.
Surface-enhanced Raman scattering (SERS) probes and labels exploit surface-enhanced Raman signatures of specifically chosen reporter molecules and intrinsic biomolecules in the plasmonic near field of gold and silver nanostructures. They offer several advantages over other optical labels and sensors with respect to sensitivity and selectivity, mobility, and biocompatibility. Here, the multifunctionality and versatility of SERS labels that come from the vibrational spectroscopic information and their ability to act as nanoprobes of a biological environment are discussed. Surface-enhanced Raman scattering probes have the potential to become the next-generation sensor technology for monitoring cells and tissues. They improve our understanding of cellular function and will play a major role in future theranostic applications.
