Exploring Solid-Liquid Interfaces The Role of Surface Science and Advanced Analytical Techniques

Professor Ville Jakinen from Aalto University explores advanced micro- and nanofabrication through the lens of surface characterization techniques used in biomedical research. He introduces key methods such as optical tensiometry, goniometry, and superhydrophobic surface analysis, highlighting the value of advancing and receding contact angles over static measurements. The talk showcases real-world applications—from COVID diagnostics to blood-repellent surfaces—while clarifying how contact angles arise from three-phase interactions and how hydrophobicity is driven by water exclusion. The presentation concludes with insights into protein adsorption mechanisms and future opportunities using QCMD to deepen our understanding of biofluid–surface interactions.

Presentation by Prof. Ville Jokinen

Professor Ville Jokinen is a micro- and nanofabrication researcher at Aalto University in Espoo, Finland, where he leads a group focused on superhydrophobic, self-cleaning and antifouling surfaces. His work combines silicon and polymer microfabrication, advanced surface and interface characterization (including intensive use of contact angle and surface tension measurements), and fluidics to develop new diagnostic and biomedical research tools such as COVID test platforms and blood-repellent capillaries.
