In the areas such as biotechnologies and life science
separation
analysis and detection of a target protein is achieved commonly relying on antibody-based specific interactions. Molecularly imprinted polymers against proteins are regarded as the most potential substitutes for the costly antibodies. However
successful imprinting of a protein is faced with some problems
one of which is the limited macromolecule diffusion throughout the cross-linked protein-imprinted polymer networks. Nanostructured protein-imprinted polymers can overcome this problem to a great extent
with relatively high ratio of surface area to volume and easily accessed imprinting sites. Herein
we review various approaches reported previously for constructing the nanosized protein-imprinted materials
particularly addressing the advantages and shortcomings associated with each method. The potential applications of these protein-imprinted materials are also described.
