Structure elucidation of silica-based core-shell microencapsulated drugs for topical applications by cryogenic scanning electron microscopy.

Microencapsulation of Drugs: Unveiling the Nanostructure with Cryo-SEM

Microencapsulation is a technique used to encapsulate drugs within tiny shells, allowing for controlled release and enhanced delivery. This research introduces a novel method for microencapsulating drugs using the sol-gel process and cryogenic scanning electron microscopy (cryo-SEM). The researchers developed a unique approach that allows for detailed nanostructural characterization of the formed capsules without any artifacts caused by drying. They utilized three signals generated by the electron beam scanning the specimen: secondary electrons, backscattered electrons, and x-rays. Combined, these signals provide comprehensive microstructural characterization of the studied specimen.

Cryo-SEM: A Powerful Tool for Nanostructural Analysis

Cryo-SEM, a cutting-edge imaging technique, allows for the visualization of the nanostructure of microencapsulated drugs in their native state. This method has significant advantages over traditional techniques, as it eliminates artifacts caused by drying. The researchers were able to demonstrate the successful encapsulation of two hydrophobic active molecules with a silica shell using the sol-gel process. This technology offers a promising avenue for developing novel drug delivery systems.
