This article reviews the applications of surface-enhanced Raman scattering (SERS) spectroscopy in medical diagnostics, including multiplexing and drug monitoring. Selected examples of SERS detection of DNA, bacteria, viruses, and disease-related proteins are presented. The fundamental theoretical background of SERS spectroscopy is also briefly outlined, providing insights for researchers entering this field.
In the last decade, there has been a rapid increase in the number of surface-enhanced Raman scattering (SERS) spectroscopy applications in medical research. In this article we review some recent, and in our opinion, most interesting and promising applications of SERS spectroscopy in medical diagnostics, including those that permit multiplexing within the range important for clinical samples. We focus on the SERS-based detection of markers of various diseases (or those whose presence significantly increases the chance of developing a given disease), and on drug monitoring. We present selected examples of the SERS detection of particular fragments of DNA or RNA, or of bacteria, viruses, and disease-related proteins. We also describe a very promising and elegant 'lab-on-chip' approach used to carry out practical SERS measurements via a pad whose action is similar to that of a pregnancy test. The fundamental theoretical background of SERS spectroscopy, which should allow a better understanding of the operation of the sensors described, is also briefly outlined. We hope that this review article will be useful for researchers planning to enter this fascinating field.
