Carbohydrate-Based Micro/Nanocapsules With Controlled External Surface for Medical Applications.

Area of Science:

• Materials Science
• Polymer Chemistry
• Nanotechnology

Background:

• Micro/nanocapsule applications are limited by the inability to controllably functionalize their surfaces.
• Existing methods lack robust control over surface moiety attachment.

Purpose of the Study:

• Introduce a novel interfacial polymerization method for controlled surface functionalization of micro/nanocapsules.
• Demonstrate the versatility of this method for various applications, especially in drug delivery.

Main Methods:

• Interfacial polymerization for Capsules' External Surface Control (IPCESCO) utilizes monomers with protected functional groups.
• These protected groups are incorporated into the capsule shell and later deprotected for surface modification.
• Modified mono- and oligosaccharides are suitable monomers due to well-established protecting group chemistry.

Main Results:

• IPCESCO enables the creation of reservoir micro/nanocapsules with diverse functionalities on their external surface.
• The method allows control over the number and type of moieties attached to the capsule surface.
• Demonstrated potential for tailored surface architecture and controlled release mechanisms.

Conclusions:

• IPCESCO is a robust and versatile method for creating functionalized micro/nanocapsules.
• This technology holds significant promise for drug delivery, pathogen detection, and other biotechnological applications.
