Chung-Ang University Team Develops World's Top-Performing 'Plant-Specific Reversible Adhesive Gel'

Our Chung-Ang University researchers have achieved a groundbreaking innovation in the field of plant science and agriculture. Professor Bae Jin-hye and her team in the Department of Chemical Engineering have successfully developed a plant-specific, reversible adhesive hydrogel with world-class performance.

This new hydrogel addresses the limitations of existing methods, which often cause physical damage to plants or have weak adhesion. Unlike previous approaches, our adhesive ensures consistent, strong attachment to various plant surfaces, regardless of their structure, and boasts an adhesion strength over 10 times higher than conventional non-invasive adhesives. Crucially, it can be easily detached by applying water, leaving no residue or damage.

This hydrogel is highly transparent and biocompatible, making it ideal for attaching wearable sensors to monitor plant health without interfering with photosynthesis.

The implications for precision agriculture are immense. Our research demonstrates the practical application of this hydrogel as a system for delivering plant-specific antibiotics, effectively protecting plants from bacterial infections. Furthermore, it has enabled exciting human-plant interaction experiments, such as remotely controlling a Venus flytrap's leaf using human motion signals, showcasing its potential in plant robotics and smart farming.

Professor Bae highlighted the hydrogel's high transparency and excellent biocompatibility, making it ideal for attaching wearable sensors to monitor plant health without interfering with photosynthesis. This development is poised to become a core enabling technology for next-generation agricultural advancements, including precision drug delivery, plant robotics, and smart farms. This collaborative effort with the University of California San Diego underscores our commitment to leading-edge research.
