Chitosan, a fascinating natural substance, is known for its unique properties like fighting bacteria, reducing oxidation, and absorbing harmful substances. Lately, it's gained attention in cancer treatment due to its special features. These include being easily broken down, safe for the body, flexible, having a large surface area, easy to control, and able to carry lots of drugs. Importantly, chitosan can be designed to react to cancer cells.

Several methods are used to create these tiny gels, such as polymerization, self-assembly, microemulsion, and ionic gelation. They're used in cancer treatment for delivering drugs, genes, and even for imaging cancer cells. There are many ways to make these nanogels, and each method has its own advantages.

One exciting aspect is that these gels can be made to respond to the environment around tumors. This means they can release their cargo at just the right time and place. This is a big step forward in making cancer treatments more effective.

While these chitosan-based nanogels show great promise, there are still challenges to overcome. Researchers are working on making these nanogels even better and ensuring they're safe for use in humans. The future of cancer treatment could be greatly improved by these tiny, smart gels.
