Graphene Frontiers was Pennsylvania based startup established in 2011 based on new graphene-production technology developed at the University of Pennsylvania. Graphene Frontiers used "Atmospheric Pressure Chemical Vapor Deposition" (APCVD) roll-to-roll room-pressure process to synthetically grow graphene.
In September 2013 the company was granted $744,000 from the NSF to scale their production capacity. Following this grant we discussed the company's technology and business with their CEO. In July 2014, the company raised $1.6 million and launched a new brand of highly-sensitive GFET-based biological and chemical sensors.
It seems the company is no longer in business.
