Assessing Hydrolytic Activity of Surfactant-Based Nanozymes: Methodological and Kinetic Considerations
Paolo Tecilla, Paolo Scrimin
TL;DR
This review explains how to properly measure and interpret the catalytic activity of surfactant-based nanozymes in hydrolysis reactions.
Contribution
The paper introduces methodological tools to accurately assess kinetic parameters and avoid overestimating nanozyme activity.
Findings
Improper kinetic modeling can lead to misleading claims about high nanozyme activity.
Correct experimental design and model selection are crucial for meaningful kinetic analysis.
The review focuses on hydrolysis of esters as model reactions for surfactant-based systems.
Abstract
The review critically discusses the methodological approach used to characterize the mechanism and to assess kinetic parameters in catalytic processes promoted by surfactant-based nanozymes. Using the hydrolysis of carboxylic and phosphoric esters as model reactions, it quantitatively analyzes several examples in which the catalytic system consists either of aggregates formed by non-functional surfactants or of surfactants bearing one or more reactive functions, ranging from classical nucleophiles to transition metal ions. This analysis highlights both the importance of the design of the kinetic experiments and of the selection of the appropriate experimental conditions, and the need to apply the correct model and set of kinetic equations in the interpretation of the data, in order to obtain kinetic parameters with true chemical significance. Improper kinetic modeling may lead to…
