This study is introducing a facile and novel method for synthesis of amorphous silica nanoparticles. Silica nanoparticles were synthesized by pyrolysis and combustion of high temperature vulcanization (HTV) silicone at 700 oC for 1 h. The products were investigated employing transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), dynamic light scattering (DLS), X-ray diffraction (XRD), Brunauer Emmett and Teller (BET) test and Fourier Transform Infrared (FTIR) Spectroscopy. The results indicated that the method is capable of synthesis of amorphous silica nanoparticles with sizes of mostly between 10 and 50 nm.

“…The use of a longer carbon chain gives as a result an increase in pore size from 2.4 to 3.1 nm, but it is not affected neither by the temperature (20-80°C) nor by the stirring rate (200-700 rpm). Another report have showed how to increase pore diameters of MSN from 2.7 to 4.9 just by decreasing the molar ratio between ethanol/water, reacting TEOS with n-octadecyltrimethoxysilane (C 18 TMS) at 30°C for 2 h [13]. Other attempts have been made to study the influence of temperature calcination for removing the SDA from the mesoporous structure, since conformational changes in surfactant and silica molecules take place during heating, suggesting that pore size can be controlled by calcination.…”

“…Emphasis is made in the requirements to achieve an ideal carrier, a perfect monodispersed sphere, and therefore, a qualitative evaluation of the shape and size dispersion of the particles is provided. Although many authors claimed to synthesize nanoparticles, only those showing proof of nanosized diameters [13,[15][16][17][18][19][20][21] are labeled as MSN (if no proof of crystal structure is shown by XRD). While some MCM-41 materials are listed [12,[22][23][24], only one was found for SBA-15 particles [24] in the submicron range, although resembling more an hexagonal shape, as it will be discussed later.…”

Continuous research in prominent fields such as biotechnology, biomedicine and nanopharmaceutics has brought the development of a widespread class of materials, and studies for mesoporous materials have been exponentially growing lately. The purpose of this review is to provide a useful guide for different materials, methods and configurations that have been reported in the last 5 years for the synthesis of spherical mesoporous silica particles (MSP), in the colloidal size range (1-1000 nm). MSP exhibit several limitations that must be overcome in order to enable their medical and clinical use. Surface modification of these particles will allow getting new promising characteristics of these materials, including better drug release control and biocompatibility improvement. These modified MSP could be potentially used in many biomedical applications, especially for drug delivery systems. Emphasis is made on the pore size, diameter and shape of the final particles since these parameters will establish key characteristics, i.e., drug delivery profile, loading capacity and efficiency. Graphical Abstract Spreading the use of mesoporous silica particles in biomedicine is possible by the improvement of its inner characteristics through surface modification. This may be done by chemical functionalization or by coating with macromolecular layers or brushes, thus creating novel responsive core-shell hybrid composites to be used as carriers for drug delivery applications.
