How Molecular Imprinting Creates Selective Recognition Sites
Quick fact
Molecularly imprinted polymers are often called 'plastic antibodies' because they can bind target molecules with specificity comparable to natural antibodies, but are far more stable and cheaper to produce.
Why this is interesting
Imagine creating a lock that exactly fits a specific key—but instead of cutting metal, you grow the lock around the key, then remove the key. That's the idea behind molecular imprinting, a process that creates materials with 'memory' for specific molecules.
