Mechanised nanoparticles for drug delivery.

Area of Science:

• Supramolecular Chemistry
• Nanotechnology
• Mechanochemistry
• Materials Science

Background:

• Global crises often drive scientific research, yet supramolecular chemistry has lacked platforms for application.
• Nanotechnology offers new materials capable of hosting supramolecular and mechanochemical functionalities.
• Mesoporous silica nanoparticles (SNPs) serve as effective supports for functionalization.

Purpose of the Study:

• To review the development of surface-functionalized SNPs with supramolecules and mechanically interlocked molecules (MIMs).
• To elucidate the mechanisms of controlled cargo release from these functionalized SNPs.
• To highlight in vitro applications of these novel materials in cancer therapy.

Main Methods:

• Functionalization of mesoporous silica nanoparticles (SNPs) with supramolecules and mechanically interlocked molecules (MIMs).
• Investigating cargo release mechanisms triggered by changes in pH, light, redox potentials, or enzymatic catalysis.
• In vitro studies to evaluate the efficacy of mechanised SNPs as drug delivery systems.

Main Results:

• Creation of 'mechanized SNPs,' nanoscale constructs capable of targeted cellular infiltration and triggered cargo release.
• Demonstration of controlled release of payloads from SNPs via mechanical modifications on their surfaces.
• Successful in vitro application of mechanised SNPs, showing potential for targeted cancer treatment.

Conclusions:

• The integration of supramolecular chemistry, mechanochemistry, and nanotechnology has yielded advanced materials for biomedical applications.
• Mechanized SNPs represent a promising platform for developing targeted cancer therapies with reduced patient side effects.
• Future research focuses on 'smart bombs' for selective cancer cell targeting and intracellular drug release, leading to apoptosis.
