Surface Enhanced Raman Spectroscopy - The materials difference

How SERS Differs from Raman Spectroscopy

Surface enhanced Raman spectroscopy (SERS) and generic Raman spectroscopy are often discussed in tandem as they share many similarities. However, SERS diverges from conventional Raman imaging in various ways, making each technique applicable in different scenarios.  We discussed the working principles of SERS in our previous article How Does Surface Enhanced Raman Spectroscopy Work? This …

What Substrates Can be Coated with Deposition Systems?

Sputter coating and many other deposition techniques, including PVD, have become essential tools in the research scientist’s arsenal. Modern sputter deposition systems are practically unrecognisable from their earliest counterparts, with vacuum chambers and sputtering systems now operable on the benchtop. There is often a concern that championing ease-of-usability and compactness will lead to compromises on …
