Abstract: For many years the technical challenges associated with obtaining useable signals meant that Raman spectroscopy was a technique of last resort restricted to expert practitioners. However, advances in instrument design and data analysis mean that it is now routinely used, even by non-specialists who can take advantage of its ability to record molecularly specific information with no sample preparation or even physical contact. Currently, surface-enhanced Raman spectroscopy is part of the way along a similar path, it has huge intrinsic advantages due to the very high sensitivity it offers but it has still not been adopted outside the expert user community. This talk will discuss the barriers to adoption that still exist and our efforts to overcome them by developing easy to prepare nanocomposite materials, exploiting superhydrophobic materials for sampling, developing robust calibration methods and finding examples where SERS is so effective it becomes the method of first choice. Examples will be drawn from a broad range of areas and include work on drugs of abuse, interfacial metal nanoparticle arrays, pain-free sampling with polymer microneedles,  e-cigarettes, anthrax detection and DNA damage.
