How Molecularly Imprinted Polymers Achieve Selective Recognition of Target Analytes
Quick fact
Molecularly imprinted polymers can be made to recognize a specific molecule by polymerizing monomers around that molecule; after removing the template, the polymer retains cavities with a complementary shape and chemical functionality, enabling selective rebinding of the target.
Why this is interesting
You've heard about antibodies that lock onto specific viruses—but what if a simple plastic could do the same? Molecularly imprinted polymers are synthetic materials that can recognize and bind a chosen molecule as precisely as a key fits its lock.
