In the present work. an aptasensing platform was developed for the detection of a carcinogenic mycotoxin termed patulin (PAT) using a label-free approach. The detection was mainly based on a specific interaction of an aptamer immobilized on carbon-based electrode. A long linear spacer of carboxy-amine polyethylene glycol chain (PEG) was chemically grafted on screen-printed carbon elec... https://www.getpureroutine.com/hot-sale-ethical-nutrients-mega-magnesium-powder-citrus-450g-for-sale-save-big/
