SERS Barcode Libraries: SERS Barcode Libraries: A Microfluidic Approach (Adv. Sci. 12/2020)

Can controlled diffusion of reagents together with micro‐shielding features enable the regioselective localization of different chemical processes? In article number 1903172, Josep Puigmarti‐Luis and co‐workers present a method for the in‐situ fabrication of custom designed surface‐enhanced Raman spectroscopy (SERS) substrates as well as for the selective localization of multiple chemical reactions onto surfaces.
