which improve therapeutic efficacy while reducing side effects.SOLUTION: Nanoparticles comprise a matrix which comprises more than 50% of silicon dioxide, where the silicon dioxide has at least one surface functional group to which at least one antigen is attached, characterized in that the particles...
Silicon dioxide can play the role of "film" of the dolphin powder wrapped up, so that the powder separated from each other, in the best of the free-flowing state, to achieve the purpose of anti-caking. In addition, the silicon dioxide powder wrapped outside, with numerous internal pores ...
Silicon dioxide(SiO2)NPshave outstanding biocompatibility, low toxicity, thermal stability, crystallinity, porosity, chemical inertness, optical transparency,etc.[171,172]. These properties enable SiO2NPs for numerous applications in biological field such as drug loading, drug/gene/protein delivery, good ...
Silicais a mineral, and refers to silicon dioxide (SiO2), which is a compound composed of Silicon and Oxygen. Silica as a compound is abundant in nature and can be found in various forms, including crystalline and amorphous structures, such as quartz, sand, and glass. These different varieti...
A modified sustained release salt of diclofenac tablet comprising hydroxyethyl cellulose, silicon dioxide and anhydrous lactose as channeling agent, polyvinylpyrrolidone, talc and magnesium stearate in speacific weight ratioUS 6509037 B2 摘要 The present invention provides a novel sustained release ...
The influence of ambient, temperature and cooling rate, in determining the surface charge at the silicon/ silicon dioxide interface has been experimentally investigated. The results, in conjunction with previous work, have enabled some o... DR Lamb,FR Badcock - 《International Journal of Electronics...
amplification and modulation. The highrefractive indexof silicon in conjunction with low refractive indexsilicon dioxidehelps to confine light produced by III–V materials in sub-micron or even nano-scale dimensions. Seen only as a vision a few years ago, siliconphotonic devicesare becoming reality ...
