Area of Science:

  • Polymer Chemistry
  • Materials Science
  • Nanotechnology

Background:

  • Cyclodextrin-based nanosponges (CD-NSs) are insoluble, cross-linked 3D polymers.
  • Primarily investigated for pharmaceutical applications, especially as drug delivery systems.

Purpose of the Study:

  • To review the evolution of cyclodextrin nanosponges.
  • To categorize CD-NSs into four distinct generations based on composition and properties.

Main Methods:

  • Classification of CD-NSs into four generations: plain, modified, stimuli-responsive, and molecularly imprinted.
  • Description of the chemical composition and functional groups for each generation.

Main Results:

  • The 1st generation includes urethane, carbonate, ester, and ether nanosponges.
  • The 2nd generation features modified nanosponges with properties like fluorescence or charge.
  • The 3rd generation comprises stimuli-responsive polymers, and the 4th generation consists of molecularly imprinted polymers (MIPs) with high selectivity.

Conclusions:

  • CD-NSs have evolved significantly, offering tailored properties for advanced applications.
  • Each generation represents a step forward in material design for specific functionalities, particularly in drug delivery.
