Area of Science:

  • Supramolecular chemistry
  • Materials science
  • Biomimetics

Background:

  • Precise control and real-time visualization of out-of-equilibrium nanostructures are challenging.
  • Understanding the formation mechanisms of self-assembled structures requires advanced monitoring techniques.

Purpose of the Study:

  • To develop a biomimetic non-equilibrium supramolecular assembly with controllable structural evolution.
  • To enable real-time visual monitoring of morphological changes using fluorescence.
  • To investigate the factors influencing the kinetics of supramolecular assembly.

Main Methods:

  • Development of a biomimetic non-equilibrium supramolecular assembly.
  • Utilizing a fluorescence shift (yellow to green) for real-time monitoring.
  • Investigating the effect of chirality, temperature, stirring, and seeding on transformation kinetics.
  • Employing a hydrogel matrix mimicking crowded intracellular environments.

Main Results:

  • Achieved spontaneous transformation from a metastable to a thermodynamically stable state.
  • Enabled real-time visual monitoring via a fluorescence shift from 580 nm (yellow) to 520 nm (green).
  • Demonstrated modulation of transformation kinetics by external factors and accelerated kinetics in a crowded environment.
  • Exploited the fluorescence-tunable hydrogel for time-dependent information encryption.

Conclusions:

  • The developed biomimetic assembly offers precise control over time-dependent structural evolution.
  • Real-time fluorescence monitoring provides insights into amyloidogenesis-like mechanisms.
  • The material demonstrates potential for creating dynamic biomimetic materials with programmable chiroptical functions and information encryption capabilities.
