Microfluidic jet splashing Charted

While preparing our Bubble-Gun system for actual skin injections using hydrogels we discovered distinct impact behavior based on jet characteristics and material stiffness. As the vast majority of (microfluidic)jet impact behavior was still uncharted territory we decided to map and explore the boundaries of these impact regimes. This work was collected into a paper titled […]

Squeezed Droplets

Following the work that we did on microfluidic jets impacting on droplets, we decided to squeeze droplets between two glass walls. This allowed us to visualise and make a deep analaysis of the generated cavity when the injection is made. Furthermore, we could use a wide range of materials, from soft solids (agarose gels) to Newtonian […]

BuBbleGun at University of Twente Alumniday 2022

During the 2022 University of Twente Alumniday, Diana gave a seminar about the history of needles and injections, needle-free injections and the remaining issues with current needle-free injection systems, which our BuBbleGun system aspires to resolve. There was a broad audience of UT Alumni and there was a extensive discussion afterwards. Additionally, the demonstration experiment […]
