Polyethyleneimine-based magnetic molecularly imprinted polymer for selective enrichment and highly sensitive determination of gallic acid in tea
{{output}}
A polyethyleneimine-functionalized magnetic molecularly imprinted polymer (MHNT-PEI@MIP) was developed for selective enrichment and detection of gallic acid (GA) in complex tea matrices. Halloysite nanotubes provided a low-cost, high-surface-area substrate wit... ...
