Prediction of Kinetically Stable Nanotheranostic Superstructures: Integral of First-Passage Times from Constrained...

Area of Science:

• Nanomedicine
• Materials Science
• Computational Chemistry

Background:

• The formation of complex nanostructures, like nanotheranostic superstructures, often involves lengthy kinetics, leading to kinetically stable states rather than thermodynamic equilibrium.
• Predicting these kinetically stable nanostructures is difficult due to the wide range of relevant timescales in nano-object formation.

Purpose of the Study:

• To develop a robust methodology for predicting kinetically stable nanotheranostic superstructures.
• To bridge the gap between molecular and macroscopic timescales in nanostructure formation studies.

Main Methods:

• Integral of first-passage times from constrained simulations (IFS) methodology.
• Constrained simulations to model nanostructure formation kinetics.
• Experimental validation of simulation predictions.

Main Results:

• The developed IFS methodology successfully predicts kinetically stable, planet-satellite nanotheranostic superstructures.
• Simulation results align with experimental observations.
• The methodology spans timescales from 10^-3 ns to 10^10 ns.

Conclusions:

• The IFS methodology provides a powerful tool for understanding and predicting the formation of complex nanostructures.
• This approach enables the rational design of kinetically stable nanotheranostic superstructures for nanomedicine applications.
• Bridging diverse timescales is crucial for advancing nanomedicine and materials design.
