Ultra-small injections penetrate the skin without causing pain

Scientists have tested a vaccine injection that could completely replace metal injections.The new technology is made from soluble material, which means that when placed on human skin, the drug/vaccine will dissolve immediately.

The new vaccine is administered simply by placing a small swab on the tip of the thumb, which is then absorbed into the skin. This form of injection can reduce the spread of the disease, improve the effectiveness of the vaccine, and save costs.

Currently, most vaccines are injected directly into the skin or muscle. However, this method requires high expertise, is expensive, can easily lead to errors, and many people are afraid or do not like being injected with a metal needle.

Scientists claim that the app is as effective as, and sometimes even more effective than, people who have been injected with metal needles. In the experimental injections, which included three flu shots, none of them caused unwanted side effects.

Previous attempts to develop micro-injections relied on silicon or metal. However, these were not safe, and sometimes they broke in the skin, leaving behind fragments. Since the invention of soluble needles, transdermal injections are becoming safer.

Previously, researchers at the National University of Singapore also invented a bandage with tiny needles attached, which can help deliver drugs such as insulin, painkillers, and even collagen into the patient's body faster and with less pain.

The bandages are fitted with dozens of tiny needles, only 0.6 mm long, that can easily penetrate the skin. This will help the medicine penetrate the skin and go deep into the patient's body.

“It looks like a patch but it has tiny needles inside it. It takes only five minutes for the drug to fully penetrate the skin,” said Kang Lifeng, a researcher at the Faculty of Pharmacy at the National University of Singapore.

Bandages like this will help many people, especially those with diabetes who often have to undergo injections and endure pain.
