Researchers from the Aristotle University of Thessaloniki in Greece have developed a new method for patient-specific medical treatment, outlined in the recently published ‘ Development of Bio-Active Patches Based on Pectin for the Treatment of Ulcers and Wounds Using 3D-Bioprinting Technology .’

 .

Using biodegradable 3D-printable inks, the Greek scientists have created transparent films that can serve as free-standing patches with both antimicrobial and wound-healing properties, via chitosan and cyclodextrin/propolis extract inclusion complexes (CCP).

 .

The patches were bioprinted and then evaluated by the research team for biocompatibility, antimicrobial levels, and wound-healing capabilities in vitro. The study also included: Ex vivo skin adhesion measurements Relative surface hydrophobicity Opacity measurement Mechanical properties Visualization Spectroscopic techniques Theoretical dimensions of the patches (a), experimental dimensions of the 3D‐printed patches after drying (b), and their difference (c), as it is calculated by Equation. The point of the study was to create a natural, nontoxic wound-dressing […]
