It is a painful thing for many patients, but they have to endure pain and discomfort. Recently, researchers at Ohio State University have developed a painless microneedle that makes injection less painful. They get inspiration from mosquitoes - especially how it pierces the human skin without causing pain from the sucking mouthparts.
By analyzing existing scientific research, the team discovered three ways in which mosquitoes can avoid pain when sucking blood. For example, they secrete saliva, which contains proteins that cause numbness. When piercing the skin, the secretions or parts that draw blood will vibrate, reducing the amount of force required. But by studying the mosquito's own feeding, the researchers discovered the fourth method. Female Aedes vexan mosquitoes are the most common mosquitoes in North America, and their mouthparts vary in length. The softer the upper lip, which is near the tip of the mouthpiece, reduces the force required to pierce the skin.
“This is very important because the softer tip piercing the skin may reduce pain because it will distort the skin,†Bharat Bhushan of Ohio State University said in a press release. Together, these forces require only one-third of the force required to apply a needle to pierce the skin.
Bhushan believes that all of these techniques can be combined in an artificial microneedle. In fact, this needle can be combined with two needles. Because of the high cost of the needle, it is unlikely that the needle will be used in all situations, but for young children or those who are afraid of getting an injection, this may be a good choice.
“We have the materials and knowledge to create such microneedles,†concluded Bhushan. “The next step is to find financial support to create and test such devices.â€
The study has been published in "Mechanical Behavior of Biomedical Materials."
