Usnic acid (UA) has been studied by its pharmacological properties; however, it presents moderate toxicity, low solubility, and absorption by biological membranes. The aim of this study was to develop poly-ε-caprolactone microsphere polymers containing UA (UA-micro) and evaluate their acute toxicity and anti-inflammatory activity. The microspheres were prepared by multiple emulsion technique (w...

In the recent past, there has been an explosion of probiotic health-based products. Many reports indicated that there is poor survival of probiotic bacteria in these products. Further, the survival of these bacteria in the human gastro-intestinal system is questionable. Providing probiotic living cells with a physical barrier against adverse environmental conditions is therefore an approach cur...

Natural food pigments are commonly utilized for the improvement of the qualitative properties of foods and/or inhibit the development of chronic and degenerative diseases. Several studies have documented the beneficial health effects of natural food pigments, such as anthocyanins, chlorophylls, and carotenoids. These effects mainly depend on the stability, bioactivity, and bioavailability of th...

The encapsulation of objects with protective layers is employed in anticorrosive coatings of the metals [1], conformal coatings in microelectronics [2], micro encapsulation of chemicals for drug delivery [3] and etc. In many research and histological practices the microscopy access to the coated sample is desirable. We report here on facile methodology for immobilization and encapsulation of ob...

Abstract-Micro encapsulation is a technology and process in which chemical substances are introduced into an environment by the use of microcapsules the process has been known at least since the 1870's and in the 1980's when serious environmental impact due to petroleum spills on land and also Earth's oceans, ravaged Earth's oceans like the Exxon-Valdez oil spill near Alaska. However, today's c...

Microencapsulation has become a hot topic in chemical research. Technology mainly used for control release and protection purposes. The sol-gel micro encapsulation approach for fragrance and aroma in porous silica-based materials leads to sustainable odorant and flavored materials with novel and unique beneficial properties. Sol-gel encapsulation of silica based micro particles considered econo...

F. Sopeña, C. Maqueda, and E. Morillo. 2009. Controlled release formulations of herbicides based on micro-encapsulation. Cien. Inv. Agr. 36(1): 27-42. Annual worldwide losses to weeds are estimated to comprise approximately 10-15% of attainable production among principal food sources. Worldwide consumption of herbicides represents 47.5% of the 2 million tons of pesticide consumed each year. How...

Against a backdrop of global antibiotic resistance and increasing awareness of the importance of the human microbiota, there has been resurgent interest in the potential use of bacteriophages for therapeutic purposes, known as phage therapy. A number of phage therapy phase I and II clinical trials have concluded, and shown phages don't present significant adverse safety concerns. These clinical...
