# Tumor-Neutralizing Patches This Microneedle Patch Can Deliver Immunotherapy Drugs to Tumor Sites By Rahul Kalvapalle | Published 2016-03-29 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/microneedle-patches References: [gizmag](http://www.gizmag.com/microneedle-patch-melanoma-cancer/42517/) & [news.ncsu.edu](https://news.ncsu.edu/2016/03/gu-immune-needle-2016/) A group of scientists and engineers led by Dr. Chao Want at [North Carolina State University](https://www.trendhunter.com/trends/electronic-patch) and the [University of North Carolina](https://www.trendhunter.com/trends/medical-implant) have developed a high-tech wearable microneedle patch that is capable of effectively, accurately and safely delivering immunotherapy drugs directly to the site of a malignant skin tumor. This patch is equipped with a number of microneedles that are loaded with special nanoparticles that contain antibodies as well as key enzymes. When the patch is placed on a melanoma tumor, blood seeps into the microneedles, causing release of antibodies. Experiments have shown that microneedle patch method is significantly more effective than conventional drug delivery that involves injecting the drug directly into the bloodstream or into the tumor. Ultimately, this microneedle patch shows a lot of promise in neutralizing dangerous tumor cells rapidly and easily. ## Trend Insights (Trend Hunter) - Score: 3.1/10 - Popularity: 47% | Activity: 37% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### What's Driving This Trend - **Wearable Drug Delivery Patches:** Advancements in microneedle patches have paved the way for targeted drug delivery, a disruptive innovation opportunity for the medical industry. - **Immunotherapy Drugs:** The development of immunotherapy drugs can potentially revolutionize cancer treatment. - **Nanoparticle-based Drug Delivery:** Use of nanoparticles as carriers for drugs is an emerging trend in the medical industry. ### Who This Affects Most - **Pharmaceuticals:** Pharmaceutical companies can leverage microneedle patches to develop more effective drugs. - **Medical Devices:** Medical device manufacturers can incorporate microneedle patches as an alternative to conventional drug delivery methods. - **Biotech:** Biotech firms researching on immunotherapy drugs can explore nanoparticle-based drug delivery platforms like microneedle patches to improve drug efficacy. ## Related on Trend Hunter - [Science-Backed Skincare Technology](https://www.trendhunter.com/trends/sciencebacked-skincare-technology-rnascence-biotechnologys-patch-delivers-r.md) - [Scar Tissue-Evading Implants](https://www.trendhunter.com/trends/medical-implant.md) - [Healing Transparent Skin Patches](https://www.trendhunter.com/trends/psoriasis-prescription-patches.md) - [Innovative Vaccine Delivery Systems](https://www.trendhunter.com/trends/innovative-vaccine-delivery.md) - [Health-Focused Non-invasive Patches](https://www.trendhunter.com/trends/super-patch.md) - [Wearable Drug Delivery Patches](https://www.trendhunter.com/trends/wearable-injector.md) - [Injection-Free Insulin Patches](https://www.trendhunter.com/trends/cequr-simplicity.md) - [Stick-On Supplements](https://www.trendhunter.com/trends/patch-up.md) - [Drug-Free Nutrient Patches](https://www.trendhunter.com/trends/nutripatch.md)
