Microencapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules, with useful properties. [ 1 ] [ 2 ] In general, it is used to incorporate food ingredients , [ 3 ] enzymes , cells or other materials on a micro metric scale.
Microencapsulation is a valuable technique for local, regional and oral delivery of therapeutic products as it can be implanted into numerous tissue types and organs. For prolonged drug delivery to the treatment site, implantation of these drug loaded artificial cells would be more cost effective in comparison to direct drug delivery. Moreover ...
In polymer chemistry, in situ polymerization is a preparation method that occurs "in the polymerization mixture" and is used to develop polymer nanocomposites from nanoparticles. There are numerous unstable oligomers ( molecules ) which must be synthesized in situ (i.e. in the reaction mixture but cannot be isolated on their own) for use in ...
Microencapsulation is the most common method to develop self-healing coatings. The capsule approach originally described by White et al., using microencapsulated dicyclopentadiene (DCPD) monomer and Grubbs' catalyst to self-heal epoxy polymer [ 59 ] was later adapted to epoxy adhesive films that are commonly used in the aerospace and automotive ...
The Journal of Microencapsulation is a peer-reviewed scientific journal that covers research on the preparation, properties, and uses of individually encapsulated novel small particles, as well as improvements to techniques using micro and nano particles in industrial, engineering, pharmaceutical, biotechnology, and research applications.
Liquid-liquid extraction is a method used to separate an analyte from a complex mixture; with this method compounds separate based on their relative solubility in different immiscible liquid phases. [ 201 ] [ 202 ] To overcome some of the disadvantages associated with common bench top methods such as the shake-flask method, [ 203 ] Microfluidic ...
Microscopy methods generate images of individual nanoparticles to characterize their shape, size, and location. Electron microscopy [2] and scanning probe microscopy are the dominant methods. Because nanoparticles have a size below the diffraction limit of visible light, conventional optical microscopy is not useful.
The most common method of preparation of artificial cells is through cell encapsulation. Encapsulated cells are typically achieved through the generation of controlled-size droplets from a liquid cell suspension which are then rapidly solidified or gelated to provide added stability.
