Highly efficient sers test strips
WebThe first step is the fabrication of a test strip. The temperature of the microheater was optimized to 65 °C for strip fabrication. A blank strip (∼4 cm × 0.5 cm) was directly dipped into the colloidal AgNPs vial for 5 seconds and then was quickly pulled out with a following baking for 1 minute with the microheater. WebLabel-free SERS is a powerful bio-analytical technique in which molecular fingerprinting is combined with localized surface plasmons (LSPs) on metal surfaces to achieve high sensitivity. Silver and gold colloids are among the most common nanostructured substrates used in SERS, but since protein-rich samples such as serum or plasma can hinder the …
