PVA Nanofibers Double Functionalized with Gold Nanoparticles as Potential Plasmon Sensor
Original language description
Polymeric nanofibers, characterized by a high volume-to-surface ratio, are used to functionalize biomolecules and metal nanoparticles. They are fabricated via electrospinning, which elongates a polymeric solution under high voltage. Nanofibers find applications in filters, nanocomposite reinforcement, tissue engineering, and sensors. Sensors, important in medicine, food, and environmental control, generate signals upon interaction with analytes. Combining electrospun nanofibers with nanomaterials, like metal nanoparticles exhibiting localized surface plasmon resonance (LSPR), enhances sensor capabilities. LSPR involves collective electron oscillations on nanoparticle surfaces, causing light absorption and scattering. This work presents polyvinyl alcohol (PVA) nanofibers double-functionalized with gold nanoparticles as potential plasmonic sensors. The PVA double-functionalization with gold nanoparticles results in a sharp plasmon peak at 528 nm. Finally, the proposed sensor showed to sense a small molecule, such as mercaptoundecanoic acid (MUA). MUA incubation resulted in a red-shift of 13 nm proving the sensor plasmonic feature.
