Belfast Researchers Develop Microneedle Cancer Patch

Researchers at Queen's University Belfast have engineered a novel dissolvable 3D-printed patch to enhance the treatment of localized skin cancer. This groundbreaking patch features microscopic needles that penetrate the skin's outer layer without causing bleeding.

These microneedles are designed to deliver two anti-cancer agents, curcumin and 5-fluorouracil, directly to the site of the cancer. This targeted approach aims to simplify treatment, reduce the need for frequent topical applications, and avoid more invasive procedures like injections, thereby making skin cancer therapy less painful and more convenient for patients.

The development utilizes a unique one-step 3D-printing method. This process integrates the anti-cancer drugs directly into a printable resin during the microneedle fabrication. This ensures better skin penetration, increased drug efficacy, and a controlled release mechanism.

Professor Dimitrios A Lamprou highlighted the potential for patient-friendly solutions, noting that dissolving microneedle systems could significantly decrease discomfort and reduce medical waste from sharps. The research, published in Advanced Healthcare Materials, suggests a future where advanced manufacturing technologies enable precise, personalized, and accessible healthcare, potentially extending to vaccines and other vital medications.
