Its prompt...
In multienzymes cascade reaction, the inter‐enzyme spacing is supposed to be a factor affecting the cascade activity. Here, a simple and efficient Y‐shaped DNA scaffold is assembled using two partially complementary DNA single strands on magnetic microspheres, which is used to coimmobilize glucose oxidase (GOD) and horseradish peroxidase (HRP). As a result, on poly(vinyl acetate) magnetic microspheres...
