Microstructured surfaces reduce platelet adhesion, a key factor in transfusion medicine. FluidFM technology enables precise surface modifications to inhibit platelet attachment, potentially extending platelet storage and improving medical devices.

Area of Science:

  • Biomaterials Science
  • Surface Engineering
  • Transfusion Medicine

Background:

  • Platelet storage is limited to 72 hours due to dysfunction and contamination risks.
  • Developing methods to reduce platelet adhesion is crucial for transfusion medicine and medical devices.

Purpose of the Study:

  • To investigate how microstructured surface geometries and distances affect platelet adhesion.
  • To explore the potential of FluidFM technology in creating antifouling surfaces.

Main Methods:

  • Fabrication of microstructures (circles, Pacman, lines, grids, triangles) using FluidFM technology on glass surfaces.
  • Characterization of microstructures using Atomic Force Microscopy (AFM).
  • Quantification of adhered platelets using Confocal Laser Scanning Microscopy.

Main Results:

  • Platelet adhesion was significantly influenced by microstructure geometry and peak-to-peak distance.
  • Circular and Pacman-like structures showed reduced adhesion, especially at 10 μm distance.
  • All microstructured surfaces exhibited lower platelet adhesion than unstructured controls.

Conclusions:

  • Microtopographical modifications effectively inhibit platelet attachment.
  • FluidFM technology can fabricate precision microstructures for antifouling applications.
  • This study provides a mechanistic model for geometry-dependent platelet-surface interactions.
