Dear Friends and Colleagues,

It is our pleasure to announce a new aquaphotomics webinar, first one this year, marking the beginning of a spring season, and hopefully a successful year for all of us.

This time, we have a pleasure to host the lecture of Prof. Tomohiro Hayashi, from Tokyo Institute of Technology, who will be talking about the role of water in the mechanism underlying bio inertness of materials.

Prof. Hayashi is a regular attendant of the Aquaphotomics Conferences, and his lectures are always advanced and very inspiring.

Please find short abstract of his lecture below. The webinar will be held using Zoom platform, 1h for the lecture and 30 min for discussion; free for all who wish to participate. All you need to do is to sign up for attendance using the “Sign up” form provided below.  

The webinar will be held in English, and it will be recorded and made available on the Aquaphotomics YouTube channel shortly afterwards, with Japanese subtitle.

We are looking forward to seeing you at the Aquaphotomics Spring Webinar!

Title: Mechanism underlying anti-biofouling: behavior of molecules at bio interfaces

Abstract: Although surfaces rejecting adsorption of biomolecules and adhesion of cells and microorganisms (anti-fouling surfaces) are highly demanded, designs of these surfaces still involve difficulties because of the lack of understanding of the underlying mechanism. We first discuss the mechanism underlying the bio inertness of oligo (ethylene glycol)-, zwitterionic-, DNA, and peptide-terminated self-assembled monolayers (SAMs) by investigating the interfacial behavior of water molecules by surface force and surface-sensitive vibrational spectroscopic techniques. Our surface force measurements evaluating the interaction between SAMs in a physiological condition revealed that all investigated bioinert SAMs exhibited water-induced repulsion. In contrast, bio adhering SAMs do not show repulsion. Surface-enhanced infrared absorption spectroscopy unveiled the characteristic hydrogen bonding state of water molecules near the nonfouling monolayers. These results exhibit that interfacial water plays the role of a physical barrier to prevent bioadhesion.
