Polymeric Micelles in Colorectal Cancer Therapy: A Comprehensive Review of Nano-drug Delivery Strategies, Copolymer Types, Physicochemical Characteristics, and Therapeutic Applications

Abstract

Polymeric micelles are becoming the method of choice for a nano-drug delivery system, especially in colorectal cancer treatment. These tiny structures have become popular for their amazing qualities that make drug delivery more efficient and therapies better. Colorectal cancer, also known as colon cancer, is one of the most common and deadly cancers in the world. Traditional chemotherapy is good, but it has big downsides, like harming other parts of the body and making people sick all over. Polymeric micelles give a new way to fix these problems by being easier on the body, breaking down naturally, and staying in the blood longer. The polymeric micelles, which are loaded with drugs, are sheltered within the tumor, which leads to a reduction in off-site effects and an increase in the targeting and accumulation of chemotherapeutics at the cancer site. This review paper elaborates on the current status of polymeric micelles as a method for nano-drug delivery for chemotherapy, emphasizing their efficacy in managing cancer. The paper also talks about the various types of copolymers that are used to create polymeric micelles, the different types of micelles, their physicochemical properties, the preparation process, characterization, and their application in cancer diagnostics.
