Special Issue Information

Dear Colleagues,

Nanogels and microgels are polymeric materials that have become essential in nanotechnology and biomedicine due to their malleable properties and versatile functionality. Nanogels offer significant advantages in drug delivery by efficiently encapsulating therapeutic agents and facilitating controlled release, while microgels are widely employed in tissue engineering and soft actuator applications due to their high loading capacity and ease of processing. Both nanogels and microgels can be engineered to respond to environmental stimuli, rendering them suitable candidates for “smart materials”. Furthermore, fundamental research on nanogels and microgels continues to deepen our understanding of soft matter physics and chemistry.

This Special Issue, titled “Nanogels and Microgels: Fundamental Studies, Applications, and Emerging Trends”, aims to showcase recent advances in this emerging field. Topics of interest include, but are not limited to, the following: the volume phase transition of gels, swelling and collapse dynamics, responsive behaviors to external stimuli, new theoretical/experimental methods for characterizing gels, and novel applications of gels in the broad areas of science and technology. Review papers offering perspectives on nanogels and microgels are also welcome.

The aim of this Special Issue is to deepen our fundamental understanding of the structure, dynamics, and material properties of nanogels and microgels, facilitating their broad range of applications across various fields.

Understanding the adsorption features of polymer microgels with different chemical compositions and structures is crucial in studying the mechanisms of respective emulsion stabilization. Specifically, the use of stimuli-responsive particles can introduce new properties and broaden the application range of such complex systems. Recently, we demonstrated that emulsions stabilized by microgels composed of interpenetrating networks (IPNs) of poly-N-isopropylacrylamide (PNIPAM) and polyacrylic acid (PAA) exhibit higher colloidal stability upon heating compared to PNIPAM homopolymer and other relevant PNIPAM-based copolymer counterparts. In the present work, using pendant drop tensiometry, we studied the evolution of water–tetradecane interfacial tension during the adsorption of PNIPAM-PAA IPN particles, comparing them with single-network P-(NIPAM-co-AA) and PNIPAM microgels. The results showed that, despite having the same chemical composition, copolymer particles exhibit completely different adsorption behavior in comparison to other microgel architectures. The observed disparity can be attributed to the nonuniform distribution of charged acrylic acid groups within the P-(NIPAM-co-AA) network obtained through precipitation polymerization. Oppositely, the presence of IPN architecture provides a uniform distribution of different monomers inside respective microgels. Additionally, hydrogen bonding between PNIPAM and PAA subchains appears to reduce the electrostatic energy barrier, enhancing the ability of IPN particles to successfully cover the liquid interface. Overall, our findings confirm the efficiency of using PNIPAM-PAA IPN microgels for the preparation of oil-in-water emulsions and their stability, even when the temperature rises above the lower critical solution temperature of PNIPAM.
