In situ synthesized eRAFT polymers for highly sensitive electrochemical determination of AFB1 in foods and herbs

A controllable Y-shaped DNA structure assisted aptasensor for the simultaneous detection of AFB1 and OTA based on ARGET ATRP

“…We processed the samples according to the reported literature. 23 The test samples were malt, astragalus and almond. Each sample was crushed and sifted through a 50-mesh sieve, and 2 g of sample powder was accurately weighed and added into 10 mL of 60% methanol solution for cold immersion for 24 h. The sample solution was ultrasonically extracted for 2 h, and the extract was centrifuged at 8000 rpm for 5 min.…”
