The ATRP initiator was introduced onto the surface of SiO 2 nanoparticles, as shown in Scheme 1a. SiO 2 nanoparticles (5.0 g) were dispersed in dehydrated toluene (25 ml) by sonication. APTES (2.7 ml, ...

The physical properties of these (PMMA/SiO 2) hybrid films were evaluated through thermogravimetry, UV-vis spectroscopy, transmission electron microscopy (TEM) and small-angle X-ray scattering ...

This means that siRNA demonstrates significant potential for therapeutic use, given its capacity to control protein levels. However, one of the main drawbacks with siRNA is that researchers have had ...

The surface of a Qβ virus-like particle is shown with a single coat protein isolated for clarity. The green and red highlights mark the two ends of the coat protein and the location where the heparin ...

Silica nanoparticles may make oral insulin possible by safely enhancing drug absorption through the intestinal wall in obese mice.

A new process enables printing of nanometer-scale quartz glass structures directly onto semiconductor chips. A hybrid organic-inorganic polymer resin is used as feedstock material for 3D printing of ...

Researchers have developed a method for preparing methylammonium-lead bromide hybrid nanoparticles with extraordinary luminescence. They have successfully increased the luminescence efficiency of ...

Scientists at the Indian Institute of Science (IISc) have developed a new approach to potentially detect and kill cancer cells, especially those which form a solid tumour mass. They have created ...

The most widely available materials of the Earth's crust include natural silica and silicates, which are primarily crystalline. Because of their excellent biocompatibility, heat resistance, low ...
