Using Raman Microscopy to Monitor the Surface Modifications of Disordered Array of Gold (Au) Covered Silicon Nanowires for SERS Biosensing

The combination of a microscope and a Raman spectrometer provides insights to a multi-stepped surface modification process to fabricate a biosensor for avidin detection using biotin-modified, gold-coated silicon nanowires (Au/SiNWs) deposited on a glass substrate. It is demonstrated that the silicon nanowires morphology enhances light absorption in the overlaying Au layer. In addition, the Raman spectra unequivocally confirmed that the composite structure (SiNWs + Au + Cysteamine + Biotin) can effectively bind the target molecule avidin through specific receptor-ligand interactions.

Polymers are large molecules made of long chains of repeating units. Naturally-occurring or synthetic, they often form glass or semi-crystalline structures rather than crystals.

Because they are such versatile materials, polymers are ubiquitous in daily life. Traditional materials such as wood and metal are being replaced with newly engineered polymers that are lighter, easier, and less expensive to manufacture. View videos, webinars and application notes to see how you can help create new polymers for everyday items.
