It has also been used in theranostic and diagnostics applications, which can provide valuable insights into treatment efficacy and disease progression, enabling personalized and optimized therapeutic interventions. Clinical studies have validated the effectiveness and safety of MN in various diseases. For instance, MN-based insulin delivery systems have demonstrated improved glycaemic control and reduced hypoglycaemic events in patients with diabetes mellitus. Likewise, MN patches have shown enhanced immune responses compared to traditional needle injections, offering a promising approach to vaccine delivery. These studies underscore the potential of MN in healthcare delivery by offering minimally invasive and patient-friendly solutions.
