Highly Sensitive and Stable Copper-Based SERS Chips Prepared by a Chemical Reduction Method
Cu chips are cheaper than Ag and Au chips for practical SERS applications. However, copper substrates generally have weak SERS enhancement effects and poor stability. In the present work, Cu-based SERS chips with high sensitivity and stability were developed by a chemical reduction method. In the pr...
