Sugary Goo Delivers Medicine: A Review of Polysaccharide Hydrogels for Drug Delivery

This review summarizes recent progress in using polysaccharide-based hydrogels to deliver therapeutic biomolecules. Polysaccharides like alginate, chitosan, and hyaluronic acid can be formed into hydrogels that can protect biomolecules from degradation and control their release, making them promising drug delivery systems.

Review article

The paper primarily summarizes existing research rather than presenting new experimental findings. Its value lies in compiling and synthesizing information, but it doesn't directly advance the field through new data.

Limited clinical translation

While the review highlights promising in vitro and in vivo (animal model) results, there's limited discussion of clinical trials or successful translation to human therapies. This gap emphasizes the need for further research to validate the efficacy and safety of these systems in humans.

Lack of detailed comparison

The review covers numerous polysaccharide types and hydrogel formulations but doesn't offer a detailed comparison of their relative advantages and disadvantages for specific applications. This makes it harder to draw clear conclusions about which materials are best suited for certain drug delivery needs.

Rating Explanation

This review provides a valuable and well-organized overview of a promising area of drug delivery research. It effectively summarizes existing knowledge and identifies future directions. While it lacks new experimental data and detailed comparisons, its comprehensive scope and clear presentation make it a strong contribution to the field. No conflicts of interest were identified.
