Cyclodextrin-Based Microcapsule Materials - Their Preparation and Physiochemical Properties

Abstract

Microencapsulation is a technique devoted to entrapping core material inside one or more polymeric coatings. Cyclodextrins (CDs) and its various derivatives are used as functional building blocks because of their unique physical properties. As well CDs possess, the ability to form well-defined host/guest inclusion complexes with lipophilic guests in aqueous solution or polar organic solvents. This review covers literature over the past decade concerning the design of microcapsules containing CDs and their physiochemical properties. Various applications of CD-based microcapsules are anticipated due to their unique surface functionalization, specific morphology, and the occurrence of a complex tertiary structure. The following themes will be addressed in this review: i) the development of CD-based microcapsules, ii) the physiochemical properties of CD-based microcapsules, and iii) the complexation thermodynamics between CDs and target molecules will be examined due to the limited availability of research corresponding to microcapsule results.

Review: A History of Cyclodextrins

“…In recent years, a relatively large number of generalist reviews has been published on practically all of these aspects of CDs, so many that it would not be feasible to cite them all. I chose to highlight those that concern research in chemistry and macromolecular chemistry, − supramolecular chemistry, − catalysis, , membranes, , aromas, foods, , agrochemistry, biotechnology, enzyme technology, cosmetics, − , pharmacy and medicine, − textiles, − ,− chromatography, − microencapsulation, nanotechnologies, − click chemistry, analytical chemistry, remediation, , and decontamination. , Several books (Table ) ,,,,, and series − can also be consulted on the different aspects of CDs including their description, characterization, properties, derivatives, supramolecular chemistry, and applications.…”

Self-assembly of cyclodextrin–oil inclusion complexes at the oil–water interface: a route to surfactant-free emulsions

“…The hydrogen bonding below and above the ring leads to secondary belts which increases the rigidity of the b-CD and hence causes low solubility. 21 In contrast, a-CD and g-CD do not have secondary belts hence their structures are exible and are therefore very soluble due to the availability of free hydroxyl groups. It has been reported that that hydrogen bonding assists the threading of CD along the chain of the guest molecule.…”

“…Recent research on CD is also very active in environmental fields such as water and wastewater treatment. Different comprehensive reviews [ 12 , 13 , 14 , 15 , 16 ] have been reported on this topic.…”
