Scanning electron microscope image shows organogel fibers in ethyl acetate. Researchers have created organic gel nanomaterials that could be used to encapsulate pharmaceutical, food, and cosmetic products and to build 3-D biological scaffolds for tissue engineering. Using olive oil and six other liquid solvents, the scientists added a simple enzyme to chemically activate a sugar that changed the liquids to organic gels.

A team of University of Alberta researchers has created technology to regrow teeth--the first time scientists have been able to reform human dental tissue.
