Nanoscale carbon-based materials in protein isolation and preconcentration

•Applications of nanoscale carbon-based materials in protein isolation are reviewed.•Carbon-based materials with various morphologies are discussed.•Future perspectives in protein isolation and separation are discussed.

This review provides an overview of the current research on nanoscale carbon-based materials as new adsorption materials in the isolation and preconcentration of protein species from biological sample matrices for ensuing bioscience investigations, or achieving enrichment prior to detection. In addition, we discuss future perspectives in related research fields.
