Introduction Triarylmethyl radicals (trityls) EPR oxygen sensors are characterized by a narrow EPR Line Width (LW) and high signal to noise ratio for EPR spectra or images. Trityls are also characterized by a good in vivo half-life compared to other soluble probes (nitroxides). However, one limitation of these sensors is their very low LW variation (∆LW) compared to particular probes. Oxygen is...

Edible films and coatings are layers of edible biopolymers (proteins, lipids polysaccharides) that can be used as an alternate for plastic packaging materials, because is causing environmental pollution it deteriorate human health when come in contact with the food product. Along their environment friendly nature they carry anti-oxidants, anti-microbials, anti-browning agents, neutraceuticals, ...

Encapsulation in the food industry is a process in which one or more ingredients or additives (core) are coated with an edible capsule. The use of liposomes is among the many forms of encapsulation of food ingredients. It consists of a sort of microscopic lipid vesicles, where due to the lipophilic and hydrophilic portion of its constituents, substances of various natures can be encapsulated, a...

The concept of polymeric nanoparticles for the design of new drug delivery systems emerged a few years ago, and recent rapid advances in nanotechnology have offered a wealth of new opportunities for diagnosis and therapy of various diseases. Recent progress has made possible the engineering of nanoparticles to allow the site-specific delivery of drugs and to improve the pharmacokinetic profile ...

The development of green synthesized polymeric nanoparticles with anticancer studies has been an emerging field in academia and the pharmaceutical chemical industries. Vegetable oils are potential substitutes for petroleum derivatives, as they present a clean environmentally friendly alternative available abundance at relatively low prices. Biomass-derived chemicals can be converted into monome...

Pesticides are widely used in producing food to control pests. However, it has been determined that synthetic pesticides present severe toxicity (residual), while they also result environmental contamination and development of high-level resistance some insect species. Due this, these susbtances have banned or restricted many countries, which reduced the number agrochemicals can be for pest con...
