Breakdown across primary industry groups indicates interest in CNTs across a wide range of industry types ranging from semiconductors, energy and biomedical (Figure ) with the latter accounting for a smaller fraction. Amongst the top 50 deals (in terms of deal size) in the area of CNTs over the last decade, majority appear to be in the material resources, information technology and business to business segments (Figure ). Energy and healthcare sectors account for very few deals of large magnitudes. In the first quarter of 2022, OCSiAl received the largest capital investment of nearly 300 million USD from a group of venture capitalists. Similarly, significant capital investments but of a smaller magnitude were also received by JEIO Co and Nano-C in 2022. JEIO Co, a South Korean company manufactures CNTs specializing in their applications in batteries (Li-ion batteries) while Nano-C appears to specialize in SWCNT manufacturing with possible use/applications in sensors and electronics. In addition, Nano-C also appears to manufacture SWCNT ink that can be deposited on the surface using a variety of printing methods. 217
