This study aimed to develop and validate an analytical methodology based on derivative spectrophotometry to determine the true concentration of ginger (ZEO) and rosemary (REO) essential oils in nanocapsule redispersible powder formulations. Second-order derivative spectrophotometry made it possible to nullify the interference of nanocapsule compone...

Inorganic nanoparticles are nanomaterials with a central core composed of inorganic specimens, especially metals, which give them interesting applications but can impact the environment and human health. Their short- and long-term effects are not completely known and to investigate that, alternative models have been successfully used. Among these,...

In this study, we evaluated the toxicological and antiproliferative effects of B. glabra Choisy bract extract (BGCE) in its free and loaded into liposomes forms administered to C. elegans mutants with let‐60 gain‐of‐function (gf). Our results demonstrated that the concentration up to 75 µg CAE/mL of BGCE was safe for the worms. Notably, we develope...

Cardiovascular diseases are one of the major causes of deaths around the world. The leading cause is related to high cholesterol levels; therefore, controlling these levels has been a successful strategy. Among the drugs used for this purpose, atorvastatin (ATV) has great efficacy; however, some side effects reduce patient adhesion. In this context...

Nanoformulations containing zein nanoparticles (ZN) can promote the stability and protection of molecules with acaricidal activity. The present study sought to develop nanoformulations with ZN associated with cypermethrin (CYPE) + chlorpyrifos (CHLO) + a plant compound (citral, menthol or limonene), characterize them, and verify their efficacy agai...

In this study, we evaluated, in a pioneering way, the influence of wavelengths from the decomposition of white light on the production and physicochemical properties of silver nanoparticles (AgNPs). Bearing in mind a process of green synthesis, an extract of the bracts of Bougainvillea glabra Choisy (BgC) was used, a species native to tropical and...

The present study developed and characterized microparticles formulations containing acyclovir and curcumin co-encapsulated in order to overcome the biopharmaceutical limitations and increase the antiviral effect of both drugs. The microparticles were prepared by a spray drying methodology following the ratio 1:3 (drug:polymer), which were made by...
