Mixtures of nanometric rods and spherical micelles that are dominated by excluded volume (entropic) interactions tend to de-mix into sphere- rod-rich mesophases. Here we report the observation hybrid mesophases formed mixtures polymer-decorated sulfuric-acid-hydrolyzed cellulose nanocrystals (CNCs, rod-like particles), at high CNCs concentrations (7 wt%) where native suspensions bi-phasic (isot...

Introduction: The development of antioxidant cosmetic products based on natural added to nanotechnology is gaining more and prominence. However, some these actives are hydrophobic, which makes their placement in aqueous systems impossible. As a strategy deliver hydrophobic hydrophilic gels, nanoemulgels have been presented.
 Materials Methods: present study aimed prepare an nanoemulgel gua...

Preparation of well-ordered continuous mesoporous carbon films without the use of an intermediate inorganic template was achieved by spin coating of a thermosetting phenolic resin, resorcinol/phloroglucinol/formaldehyde, and a thermally-decomposable organic template, Pluronic F127 (PEO106–PPO70–PEO106). The carbon films were deposited onto silicon, platinum/ silicon, copper, glass, and quartz s...

Early in this study, CdTe/ZnS core/shell quantum dots (QDs) were encapsulated in carboxylated Pluronic F127 triblock polymeric micelle, to preserve the optical and colloidal stability of QDs in biological fluids. Folic acid (FA) was then conjugated to the surface of QDs for the targeted delivery of the QD formulation to the tumor site, by exploiting the overexpressed FA receptors (FARs) on the ...

The triblock copolymer Pluronic F127 (PF127) is frequently used in colloidal and pharmaceutical formulations. Concentrated aqueous solutions of PF127 (>15 wt %) are known to undergo thermogelling (i.e., a sol-to-gel transition upon heating), which is attributed to the formation of a volume-filling cubic array of micelles. Here, we report that thermogelling can occur at much lower PF127 concentr...

Pluronic F127 polyol, a block copolymer of propylene oxide and ethylene oxide, was studied as an alternative to agar in culture media for nematodes, bacteria, fungi, actinomycetes, and plant tissues or seedlings, At a polyol concentration of 20% w/v, the culture media, semi-solid at room temperature (22 C) but liquid at lower temperatures, had minimal effects on the test organisms. Most of the ...

O Pluronic F98 e F127 possui maior porcentagem hidrofílica (70 wt%), no caso do 80% F98. artigo consiste na comparação parâmetro HLB da sua influência formação das Nanopartículas de Ouro. São escolhidas essas nanopartículas, por apresentarem baixa toxicidade, como também ser eficaz em aplicação medicinal. câncer estômago exibe alta incidência. Há a dos compostos com um núcleo hidrofóbico polióx...
