Dynamic Liquid-Crystal Colloids with Biomimetic Actuation, Recognition, and Adaptation

22st national competition for scientific and technical research

New materials: fundamentals and applications

Senior Researcher : Alberto Concellón Allueva

Research Centre or Institution : Instituto de Nanociencia y Materiales de Aragón. Universidad de Zaragoza

Abstract

Nature is an endless source of inspiration thanks to its sophisticated processes for motion control, signal recognition, and information transmission. However, understanding the mechanisms behind these phenomena and applying them to the design of advanced materials remains one of the major challenges in science. This project addresses that challenge through the development of novel artificial self-assemblies capable of behaving as autonomous biomimetic systems.

Our approach focuses on dynamic liquid crystal colloids (DLCs), a system we pioneered in previous research, which exhibits remarkable similarities to cells in both structure and function. DLCs stand out for their responsiveness to external stimuli and their versatility in incorporating functional molecules within them. These features make them an ideal platform for creating next-generation smart materials with biomimetic properties such as actuation, supramolecular recognition, and autonomous adaptation to changing environments.

The research plan is organized around two main objectives inspired by natural systems: (1) To design DLCs capable of generating motion or performing work through mechanisms such as pumping or translocation; and (2) To endow DLCs with memory and adaptive capabilities, emulating functions observed in living systems.

In essence, this project aims to lay the groundwork for advanced supramolecular platforms capable of autonomously responding to specific stimuli in complex environments. Gaining insight into the structure-activity relationships in these systems will open new avenues in fields such as soft robotics, advanced sensing, and controlled drug delivery. Beyond scientific advancement, the project aspires to offer practical and innovative solutions that will transform the way we interact with functional materials, generating meaningful benefits for society.
