Surface-enhanced Raman spectroscopy (SERS) technology has shown broad potential in drug concentration detection, but its application blood monitoring faces significant challenges. The primary difficulty lies overcoming the interference caused by various biomolecules present serum, which can severely obscure SERS signals of target molecules. Traditional enhancement substrates are often limited to detecting single drugs and prone interference, making label-free detection multiple particularly challenging. To address these issues, we developed a novel substrate based on Au@AgNRs, undergoes two-step modification produce Au@AgDBCNRs. This innovative provides exceptional signal amplification, simultaneously allowing sensitive Moreover, our method eliminates need for serum deproteinization, enabling direct while effectively mitigating from components. cetyltrimethylammonium bromide coating Au@AgDBCNRs is an internal standard quantification without additional standards. platform significantly improves accuracy efficiency automatically integrating artificial intelligence recognize analyze spectral features. new idea therapeutic expected provide rapid, accurate, cost-effective clinical environment, great improving patient care optimizing dosage strategies.
