The Basics of Graphene
Graphene, in the simplest terms, is a single layer of graphite. In short, this revolutionary material was discovered in 2004 by scientists at University of Manchester, a feat for which they were awarded the 2010 Nobel Prize in Physics. Today, copious graphene-based studies are conducted across different disciplines including physics, chemistry, materials science, and engineering exploiting many of graphene’s unprecedented properties. Prof. Byung Hee Hong, the founder of BIOGRAPHENE, is a pioneering scientist of CVD graphene which has enabled scalable use of graphene films. Prof. Hong is also one of the scientists who first employed graphene film for biomedical applications. Following years of studies by scientists at Seoul National University and Johns Hopkins School of Medicine, BIOGRAPHENE focuses exclusively on the application of soluble graphene-based materials for biomedical applications.

Graphene Quantum Dots (GQDs)
GQDs
Graphene Quantum Dots with Excellent Biocompatibility
Among the varying types of soluble graphene-based nanomaterials, Graphene Quantum Dots (GQDs) display some of the most promising properties in terms of biocompatibility. Nanometer-sized graphene quantum dots are known to exhibit negligible toxicity with excellent stability in physiological conditions, attracting attention as bioimaging, diagnostic agents as well as drug delivery platforms. Their amphiphilic properties are advantageous in interfering with or breaking down the formation of undesirable aggregations (neuroprotein/cholesterol) in the body. With years of experience and acquired expertise, BIOGRAPHENE provides the highest quality GQDs for biomedical applications.
