Organic nanogel
Do you like this story?
Researchers have created organic gel nanomaterials that could be used to encapsulate pharmaceutical, food, cosmetic products and to build 3-D biological scaffolds for tissue engineering. Using olive oil and six other liquid solvents, the simple enzyme sugar is chemically activated to change the liquids to organic gels. These are naturally occurring enzymes which can be used to create chemically functional organogels and to reverse the process and break down these gels into their biologically compatible building blocks. Sugar activated by a simple enzyme generates a compound that self-assembles into 3-D fibers measuring approximately 50 nanometers in diameter and as the fibers entangle, a large amount of solvent gets packed together. This new organogel material could be used as biocompatible scaffolds for tissue engineering, designing membranes, drug delivery systems for pharmaceuticals and preservatives for food and cosmetics and in drug discovery, materials science, chemical technology etc.;
