Microneedles are tiny needles, typically ranging from 100μm to 2mm in length, that can be used to administer insulin to diabetes patients. Here are several ways microneedles can help diabetes patients:

• Less Painful: Microneedles require less force to penetrate the skin compared to traditional hypodermic needles, making them less painful and more comfortable for patients.
• Accurate Dosing: Microneedles can deliver precise doses of insulin, which is particularly beneficial for patients who require small doses of insulin and need frequent injections.
• Improved Absorption: Microneedles form micro-channels in the skin that enhance the absorption of insulin, making it more efficient than traditional injections.
• Convenient: Microneedles can be designed for single use and can be easily self-administered by patients at home, reducing the frequency of hospital visits.
• Reduced Risk Of Infection: As microneedles are less invasive than traditional needles and do not penetrate as deep, there is less risk of infection.

Overall, microneedles offer a promising alternative to traditional insulin delivery methods and could greatly improve the quality of life for diabetes patients.
