Molecularly imprinted polymers (MIP) based on an acrylic system have proven useful for sensing Penicillin V in aqueous solvents by the means of quartz crystal microbalances (QCM). Herein we carry that concept further by synthesizing molecularly imprinted polymer (MIP) nanoparticles (NPs) as sensitive matrices due to some considerable properties including high surface-to-volume ratio, low cost and straightforward preparation and handling. Herein, we report the sensitivity and selectivity results of MIP NPs with rapid screening method based on QCM. The approach indicates selective response of sensors to Pen V toward similar molecular structures and clearly reveals concentrationdependent reversible signals in terms of different concentration of target.
