Study on the activity of Huo–Xue–Hua–Yu decoction and its drug groups in improving fracture healing using surface-enhanced Raman scattering (SERS) spectroscopy based on gold nanoparticles

The SERS technique has great potential for providing a novel method for effectively and accurately studying the efficacy of the Huo–Xue–Hua–Yu decoction and its drug groups in improving fracture healing.
