Surface modification is essential in microfluidic applications due to the inherent hydrophobicity of polymers, which can lead to biofouling and reagent denaturation. Despite the development, challenges such as hydrophobic molecule absorption and limitations in scaling are still present. Off-stoichiometry thiol-ene (OSTE) materials have emerged as a promising alternative, offering advantages like rapid prototyping, minimal hydrophobic absorption, and customizable surface chemistries. While the thiol-ene polymerization mechanism is well understood, the fundamental understanding of thiol group binding on OSTE surfaces remains limited. Existing techniques to analyze surface groups lack the capability to confirm the stable presence of thiol groups on the surface. In our study, using Raman and X-ray photoelectron spectroscopy techniques, we investigated a potential method for enhancing the surface properties of OSTE polymer—the attachment of novel linkers to the surface. We have demonstrated our synthesized compound efficiency by binding gold nanoparticles to the OSTE surface. Our findings indicate that chemical reactions involving double bonds with the material surface hold the most potential for effective surface modification for gold binding. |
