Sol-Gel Silica Nanoparticles in Medicine: A Natural Choice. Design, Synthesis and Products

open access: yesMolecules, 2018
Silica is one of the most abundant minerals in the Earth’s crust, and over time it has been introduced first into human life and later into engineering. Silica is present in the food chain and in the human body. As a biomaterial, silica is widely used in

Synthesis and Characterization of Modified Silica Gel from Teff Straw Ash Using Sol-gel Method

open access: yesNext Materials
Teff straw ash was first converted into sodium silicate solution, then processed via sol-gel, producing low-density silica aerogel (modified silica gel). A one-step modification method was applied to produce modified silica gel from teff straw ash.

Silica Gel From Bagasse Ash for Methylene Blue Adsorption

open access: yesSains Natural
Most silica sources are from non-renewable natural sand or rock materials, which affect the element's diminishing availability in the environment. Because bagasse ash has a relatively high silica concentration, it can be used as a silica source to ...

Immobilization of cellulase on a silica gel substrate modified using a 3-APTES self-assembled monolayer

open access: yesSpringerPlus, 2016
Cellulase was immobilized onto silica gel surfaces pretreated with (3-aminopropyl) triethoxy-silane (3-APTES), and glutaraldehyde (GA) was used as a cross-linker.
