Perspective schematic of a stacked multilayer substrate with exposed thiol groups depicted as repeated SH along the interfacial surfaces. In biochemistry and surface chemistry, these sulfhydryl (SH) functional groups on a material’s surface form a lower-level chemical feature within the higher-level layered structure. Their presence at the interfaces enables disulfide bond formation and chemoselective conjugation, facilitating crosslinking, ligand attachment, and biomolecule immobilization. The illustration represents functional groups on a material surface rather than a specific organism.
