Who really likes needles? A brand-new episode of our Tech Briefs podcast series Here’s an Idea™ explores the emergence of micro-ones.

Learn all about how an array of microneedles can deliver drugs in a more precise way than the needle and syringes that we're used to. The Velcro-like micro option is less painful – and more effective, it turns out.

And the devices are especially valuable during a pandemic. (Listen to the brand-new episode below.)

Episode Highlights:

  • (0:54) Professor Ryan F. Donnelly, from Queen's University Belfast, sets the stage and explains what a microneedle is exactly, and how microneedles are being used today.
  • (11:05) Stanford Professor Joseph DeSimone details his team's 3D-printed vaccine patch that provides greater protection than a typical vaccine shot.
  • (18:48) Sandia researcher Ronen Polsky discusses efforts to use microneedles to draw out interstitial fluid, which can offer early detection of diseases.

Sandia National Laboratories materials scientist Ronen Polsky positions a prototype 3-D-printed microneedle holder on the arm of Sandia science writer Mollie Rappe. Rappe participated in a clinical trial to see the best length of needle to extract the interstitial fluid on the path to track the physiological condition of soldiers.
