Stimulated Raman scattering (SRS) microscopy allows label-free chemical imaging based on vibrational spectroscopy. Narrowband excitation with picosecond lasers creates the highest signal levels and enables imaging speeds up to video-rate, but it sacrifices chemical specificity in samples with overlapping bands

An aqueous-soluble melamine polymer was condensed into nanoparticles by specific heterocycle binding interactions with 5-fluorouracil (5-FU) or cyanuric acid (CA). Small-molecule/polymer recognition of this type exhibits a clear exothermic binding signature and is sufficiently robust to induce macromolecular assembly in
