One of the current limitations surrounding surface-enhanced Raman scattering (SERS) is the perceived lack of reproducibility. SERS is indeed challenging, and for analyte detection, it is vital that the analyte interacts with the metal surfa...
Towards the in vivo prediction of fragility fractures with Raman spectroscopy [0.03%]
