Abstract
Abstract Metal‐free graphitic carbon nitride (g‐C 3 N 4 ) as a newly emerging nanomaterial has been employed in the biomedical field because of its special optical and electrical characterizations. This review summarizes diverse methods for preparing g‐C 3 N 4 ‐based materials, and discusses contemporary advancements in biosensors, photocatalytic sterilization, photodynamic therapy, drug carrier, and biological imaging. The biosafety and toxicity evaluations of g‐C 3 N 4 ‐based materials are discussed as well. The review ends with an overview and several insights on the challenges and opportunities of g‐C 3 N 4 ‐based nanomaterials in this burgeoning field. This review is expected to provide inspiration for developing future g‐C 3 N 4 ‐based materials for the biomedical applications.
