Abstract
- WOS:000452363700066 A novel folic acid-imprinted quartz crystal microbalance (QCM) nanosensor in order to detect folic acid depending on the fabrication of folic acid-imprinted polymer film on a QCM electrode was developed with methacrylamidoantipyrine-gadolinium (III) [MAAP-Gd(III)] used as a monomer for metal coordination-chelation interaction to obtain a more selective molecularly imprinted polymers (MIPs). The developed folic acid-imprinted nanosensor on the MIP/QCM detection system showed outstanding properties such as a stronger affinity of 3.07x10(7)M(-1), a short response time of 10min, wider linear range of 0-100 mu M, a selectivity of k=8.25 and lower detection limit of 0.0080 mu M. After characterizing its all features, the newly designed folic acid-imprinted QCM nanosensor was utilized to detect folic acid level in commercial follow-on baby milk in order to determine its use in real samples.
