Abstract
AIM
Aspirin is known to be a salicylate drug widely used as an analgesic, antipyretic and anti-inflammatory drug.
METHODOLOGY
Sol-gel based nanosized molecularly imprinted polymer (nMIP) has been synthesized for extraction of aspirin and its metabolites in urine followed by GC-MS/MS analysis.
RESULTS
Binding affinity of nMIP and nonimprinted polymer was found to be in the range of 70-95% and 29-45%, respectively. LOD and LOQ of aspirin and its metabolites were found to be in the range of 0.63-2.4 ng/ml and 2.07-7.68 ng/ml, respectively.
CONCLUSION
The developed method was found to be applicable for routine analysis of aspirin and its metabolites in biological samples.
