Robert Cammarata

Prof. Robert Cammarata: Cofounder

Truly a titan in Materials Science Community, Prof. Cammarata (Bob) was instrumental to the formation of NanoDirect through his cutting-edge research, mentorship, and founding role as CSO. Sadly, Bob passed away in 2016, however NanoDirect strives to continue his legacy of excellence and integrity in advancing the field. A more extensive tribute to him can be found here:


To help our customers improve quality and reliability in their products and usher in commercial manufacturing of printable and flexible electronics.


The technological foundation of NanoDirect grew out of research conducted by the Cammarata group at Johns Hopkins University that demonstrated the separation and controlled motion of nanoscale carbon-based materials. The initial commercialization research was conducted using MII Phase I funding in 2013. NanoDirect then joined the FastForward Incubator System of Johns Hopkins in 2014, where the technology was further refined and developed to create continuous flow systems that have shown the ability to separate nanomaterials by their size, shape, electrical, and chemical properties. These technologies have been successfully applied in beta tests with key industry partners leaving NanoDirect positioned for scaling and early commercialization.
