Nanoparticles are being developed to enhance drug delivery to cancer tumors, leveraging advantages such as the enhanced permeability and retention (EPR) effect. However, traditional nanoparticles often face challenges with low specificity for cancer cells, leading to inefficient delivery and unwanted side effects. Esterase-responsive nanoparticles offer a maximum targeted approach to tumor cells because they release their therapeutic payload at the tumor site under the influence of esterase activity. This review explores the role of esterase-responsive nanoparticles in drug and gene delivery, examines esterase prodrug therapy, and discusses prostate-specific membrane antigen (PSMA) targets esterase-responsive nanoparticles in prostate cancer treatment. Additionally, we reviewed the current research progress and future potential of esterase-responsive nanoparticles in enhancing drug and gene delivery.
