Sensor Array Based on Molecularly Imprinted Polymers for Simultaneous Detection of Lipoproteins
نویسندگان
چکیده
Herein we report a sensor array based on quartz crystal microbalance (QCM) to simultaneously detect two biomarkers, namely low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Selective recognition takes place through molecularly imprinted polymers (MIP) with both MIPs and corresponding non-imprinted polymer (NIP) as reference electrode. Sensor array performs highly appreciably in term of selectivity to LDL and HDL (defined through its cholesterol LDL-C, and HDL-C) when operated in 10 mM PBS. The sensor response time is less than 15 min. Furthermore, coefficients of variation indicating precision of our sensor array are at 2%–8%.
