Nanocarriers, such as liposomes, polimeric nanopactiles, dendrimers, and mezoporous silica particles, can encapsulate insuline to protect it from degradation, control it release rate, and direct it to specific tissues.

That Persistent Challenges of Conventional Insulin Therapy

To understand why nanotechnology is so compelling, one must first appreciate the limitations of existing delivery systems. Subcutaneous insulin injections, the most common method, require multiple daily administrations and are associated with variable absorption rates depending on injection site, depth, and local blood flow. Patients frequently report pain, bruising, lipodystrophy, and psychological burden. A 2020 study in Diabetic Medicine found that nearly 40% of patients intentionally skip injections due to discomfort or lifestyle interference.
