    摘要: The disclosure relates to methods and devices for measuring samples, such as biological samples, especially those at low abundance, with high sensitivity and at low cost. A sample is disposed on a shrinkable scaffold and the shrinkable scaffold is shrunk, reducing the area where the sample is distributed, so as to effectively concentrate the sample on the surface of the scaffold. In the event that a biological sample is covalently attached to a scaffold having a silica structure, the increase in signal enhancement is also due to optical effects stemming from covalent linkage of the biological sample onto the silica structure of the scaffold. Silica (SiO2) may be deposited onto a surface of a polymer film by functionalizing the surface of the polymer film to bind silica from a sol-gel solution, and coating the film with a sol-gel solution containing silica precursors, wherein solid silica from the sol-gel solution is deposited onto the surface of the polymer film. Also disclosed is an immunoassay platform comprising a silica-encapsulated first detection agent deposited on a polymer substrate.
