Lipid-based formulations constitute an important category and can be used to influence the absorption of active ingredients by means of modification of release of active ingredients.
The report also noted that "there is, however, an additional consideration for extended-release dosage forms: the inclusion of a critical release component(s) which enables the extended release of active ingredients.
Nano-delivery systems for pesticides involve entrapping the active ingredients of pesticides inside polymeric nanomaterials, to allow the slow and controlled release of active ingredients on target crops [20 22].
Besides, pesticide nanodelivery systems also have better penetration through the cuticle and allow slow and controlled release of active ingredients on the target[5, 6].
In addition, Av nano-delivery systems also have better penetration and allow for slower and more controlled release of active ingredients on target crops, compared with conventional microcapsules.
Therefore, stents with a non-degradable polymer coating showing controlled release of active ingredients have become an attractive option for the site-specific delivery of anti-restenotic agents.
Xanthan-based hydrogels can be used for encapsulating and controlling release of nutrition ingredients, therapeutic agents, and cells in food and tissue engineering applications.
This will enhance the diffusion of solvent into the cell wall, which in turn will allow the rapid release of active ingredients from the cell matrix of the plant.
Any type of triggers can be used to prompt the release of encapsulated ingredients, such as pH changes, mechanical stress, temperature, enzymatic activity, time, and osmotic force.
Nanotechnological strategies change a substance's properties and behavior in a biological environment and can potentiate the actions of plant extracts, promote sustained release of active ingredients, reduced the required dose, decrease the side effects and improve activity [ 4].
