Dr.ir. David Fernandez Rivas

The enterprising Bubble Gun researcher

In the near future, we could get our medication or vaccination with painless needle-free injections, or even smart tattoos on our skin. Researcher and entrepreneur David Fernandez Rivas is working on his (realistic) dream in Twente.  “I call it: applicable research. It’s a crossover of fundamental and applied science.”

When Fernandez Rivas came to Twente he already knew that he is not a traditional fundamental researcher.  “I’m not only passionate about curiosity-driven knowledge or academic relevant questions. I also get my energy from solving problems that have an impact on society. The more a scientist can walk with solutions closer to the market, the better it is. When a company takes over the idea or concept from academic research, a lot of know-how can be lost. Participating in a company or being an entrepreneur myself, I’m able to bridge the gap between idea and implementation.”

European Starting Grant

Therefore, co-founding the spin-off BuBclean in 2013 was a logical step for Fernandez Rivas. “My cofounder and I had a cool idea and decided: let’s give it a try. If we hadn’t done it ourselves, there would be no product today.” BuBclean was founded to develop innovative products and technology for ultrasonic cleaning. One of the first products was the Bubble Bag, a small container for improving ultrasonic baths performance.

Four years later Fernandez Rivas won the StartUpLaunch Competition in Twente with another start-up (InkBeams), based upon needle-free injection technology, that also has been patented. The InkBeams technology inspired the research project Bubble Gun, for which Fernandez Rivas has received a Starting Grant from the European Research Council. “That turned out a big boost for our project. It has really opened doors and has also given us more credibility and visibility in the market.”

44 million needles a day

The name of the project refers to a device that pushes liquid into the skin using laser-made bubbles. An important application of this method are needle-free injections of drugs or vaccines into the skin. Why needle-free? “Because 1 in every 5 persons is afraid of needles”, Fernandez Rivas says. “With the result that patients don’t complete their treatment. Besides that, we solve another problem by using fewer needles: environmental contamination. 44 million needles are used each day, worldwide, with a big risk of infection when not used properly.”

An advantage of the Bubble Gun technology is also that it does not damage the skin of the patient. “The treatment is both painless and more effective because it delivers drugs in the superficial part of the skin and with such small volumes that are imperceptible.” Fernandez Rivas thinks that within a few years needle-free injections will be part of our lives. His dream is to use the same technology to apply medical and smart tattoos on the skin, which can help reading biomedical signals from our body.

Education

The contact with undergrad and grad students is crucial for Fernandez Rivas. “For many professors in academy lately research seems to be the most important thing. For me teaching is not only happening in the classroom; I consider education as knowledge exchange. The interaction with younger scientists or students with a different background is very helpful for me. Listening to them, helps me to understand how to solve the problems of the future. I pitch my ideas in an early stage to the classroom, so that I can find weak points in my concept. I like to be challenged by critical and motivated students. Education is my most direct connection to society.”

About David Fernandez Rivas

David Fernandez Rivas (1981) came from Cuba to the Netherlands in 2007, to do his PhD in the research group Mesoscale Chemical Systems of the TNW faculty. After his post-doc, he became assistant professor (tenure track) and since 2020 he is an associate professor in Twente. He is also a research affiliate of Mechanical Engineering Department at the Massachusetts Institute of Technology (MIT).

Fernandez Rivas is member of both the Young Academy of Europe and the Global Young Academy, two international network organizations for outstanding young scientists. “It gives me the opportunity to discuss with motivated colleagues all over the world and contribute to solutions to problems affecting society on a global scale.”
