Biopolymers phase separation monitored by a plasmonic sensor.

Understanding protein-polysaccharide interactions is essential in food science and biotechnology. Prior research has shown that such interactions can lead to phase separation, but real-time monitoring remains limited. Established methods often rely on post-hoc analysis, which lacks temporal resolution. This gap motivated the development of more dynamic detection systems. No prior work had resolved the optical signatures of these interactions in real time. That uncertainty drove the exploration of plasmonic sensors for this purpose. This gap motivated the search for a technique that could track structural changes as they occur. This gap motivated the search for a technique that could track structural changes as they occur.
