Abstract
Pancreatic cancer is a highly aggressive and lethal malignancy with an exceptionally poor prognosis. Its clinical management is severely hampered by insidious early symptoms, strong invasiveness, intrinsic chemoresistance, and limited efficacy of conventional therapies. Carbon dots (CDs) have shown great promise in precision cancer theranostics owing to their excellent optical properties, high biocompatibility, controlled drug loading and release capabilities and customizable targeting features. This review critically examines the major therapeutic barriers in pancreatic cancer management, systematically summarizes the applications of CDs in pancreatic cancer imaging, targeted drug delivery, hyperthermia and pH-responsive theranostics, analyzes the current limitations of CD-based nanosystems, and discusses future development directions. This work aims to provide a rigorous theoretical foundation for the rational design and development of novel CD-mediated precision intervention strategies for pancreatic cancer.
