Researchers at the University of Adelaide have developed a 3D-printed micro-lens that can be used to see inside blood vessels, potentially improving heart attack prevention.

The micro-lens is just 0.26mm in diameter and is 3D-printed directly onto an optical fibre, allowing for minimally invasive imaging inside the body.

Unlike traditional imaging techniques that use Gaussian beams, this device uses a 'needle beam' (or Bessel beam), which stays tightly focused, providing clearer and sharper images.

Early testing in preclinical models has shown superior imaging quality, and researchers are now preparing for clinical trials to assess its potential in improving heart disease diagnosis and treatment.
