Graphene Supermarket, which offers a broad range of graphene nanomaterials, announced that they have added a new product called Q-Graphene. This is a nanomaterial that consists of hollow, porous, multi-wall carbon nanospheres with a narrow size distribution and an average particle size of less than 100 nm. The company claims that there is a high demand for this material in materials engineering for energy storage, supercapacitors, nanosensors, catalysis, and composite materials. Moreover, Q-Graphene is being considered for potential use in a variety of biomedical applications such as intracellar drug delivery, cancer treatment and high-performance bioimaging.
You can order the Q-Graphene online. It costs $100 for 1 gram (or $325 for 5 grams).
