Amsterdam-Netherlands researchers are developing laser technology that enables “substantially painless” injections without needles in a revolutionary way to relieve fear and lower vaccination thresholds.
The “bubble gun” uses a laser to push small droplets into the outer layers of the skin, says David Fernandez Rivas, a professor at the University of Twente, the research affiliate of the Massachusetts Institute of Technology, who founded the idea.
“It shouldn’t cause pain,” he said, as the process is faster than a mosquito bite and does not touch nerve endings in the skin, adding that this will be studied further.
“Within a millisecond, the glass containing the liquid is heated by a laser, creating bubbles in the liquid that pushes the liquid out at a speed of at least 100 km / h (60 mph),” he said in his lab.
“This allows it to penetrate the skin without damage. No scratches or entrances are seen.”
Rivas hopes that the present invention will not only help more people to be vaccinated, but also prevent the risk of contamination by dirty needles and reduce medical waste.
Testing of tissue samples was successfully conducted with a € 1.5 million European Union grant. According to Rivas, an application to fund the start of volunteer human testing will be submitted this month.
He said a new start-up will work with the pharmaceutical industry to test and sell “bubble gun” technology.
However, depending on research progress and regulatory issues, it may take a year or three for this method to be publicly available.
Approximately one in five Dutch people are afraid of needles, said Genk Schenck, who offers treatments to help those in severe suffering. “Needle phobia is more common than you think. People are ashamed to admit it.”
Some people are afraid to trace their fears back to traumatic childhood hospitalizations or give up control. A small number of about 1 in 1000 have deep phobias and require repetitive sessions to prepare for the jab.
“During the (coronavirus) pandemic, we can see that many people who were able to avoid it are now hitting the wall. People who need to get the Covid-19 vaccine are an important group for me this year. is.”
Patient Astrid Nysen, a 31-year-old musical actress who had 10 sessions with Schenck, says she is worried about getting vaccinated without a needle.
“It started in adolescence. When I have to look at the needle or shoot, I just want to leave. I break the place just to prevent it from being shot,” she says. I did.
