AI Technical Summary

Benefits of technology

This patented technology describes making certain types of materials that have unique properties like recognizing or binding with enzyme called Arthrin (a type of plant hormone). These specialized structures made from these compounds help make them better suited for various applications such as medicine, food products, cosmetics, etc.. They also provide technical advantages over existing methods due to their simplicity, ease of manufacturing processes, environmental friendliness, and lower costs compared to current technologies.

Problems solved by technology

Technicians skilled in studying various technical problem addressed in this patented text include finding suitable supporting materials that can effectively bind or release target compounds without causing contamination issues like residual impurities. Surfactants play key roles in capturing these targets onto surfaces through interactions between water molecule and mold plate moleculae. Natural sources of surfacemask oils were developed over several decades ago, making it possible to control the amount of each component released into air streams. Chemistry techniques involving reaction injection/melt extrusion processes have been explored to improve efficiency and productivity.
