Rutgers University scientists have devised a highly accurate method for creating coatings of biologically active materials for a variety of medical products. Such a technique could pave the way for a new era of transdermal medication, including shot-free vaccinations, the researchers said.
Writing in Nature Communications, the researchers described a new approach to electrospray deposition, an industrial spray-coating process. Essentially, the team developed a way to better control the target region within a spray zone as well as the electrical properties of microscopic particles that are being deposited. The greater command of those two properties means that more of the spray is likely to hit its microscopic target.
In electrospray deposition, manufacturers apply a high voltage to a flowing liquid, such as a biopharmaceutical, converting it into fine particles. Each of those droplets evaporates as it travels to a target area, depositing a solid precipitate from the original solution.
