IISc researchers used a micromolding technique to create the microneedles. This method involves the use of a mold that is fitted with tiny cavities to produce minuscule structures. Here are some key points on how the microneedles could help those with diabetes:

• The needles are made to be small enough to be painless for patients, yet still be effective in insulin delivery.
• They can be easily applied by patients themselves, eliminating the need for injections by healthcare providers.
• The needles may offer a more consistent insulin delivery than other methods, as they remain in the skin for a longer period of time.
• In addition to insulin delivery, the microneedles may also be able to deliver other medications to patients in need.
• The IISc researchers' microneedle design has the potential to significantly improve the quality of life for diabetes patients by improving the efficiency, safety, and convenience of insulin delivery.

Overall, the microneedles created by IISc researchers could represent a major breakthrough for diabetes treatment, potentially minimizing patient discomfort and offering improved drug delivery compared to traditional methods.
