Non-invasive real-time monitoring of these models would provide valuable insights without disrupting the cellular environment. This study explores the use of molecularly imprinted polymers (MIPs) for this purpose, focusing on insulin and lactate as biomarkers of cellular metabolism. MIP sensors were created by electropolymerizing pyrrole around insulin or lactate templates on carbon electrodes. The sensors showed high sensitivity and selectivity, with detection ranges of 20.0–70.0 pM for insulin (LOD: 2.41 pM) and 0.5–3.0 mM for lactate. These findings highlight MIPs’ potential for personalized diagnostics and therapy monitoring.Univerza v Mariboru, Univerzitetna založba20242025-01-24 11:04:53Znanstveno delo91659UDK: 60COBISS_ID: 223684355DOI: 10.18690/analipazu.14.2.39-57.2024ISSN pri članku: 2820-364Xsl
