Data from Pitchbook 203 , a database encompassing global capital markets, indicates robust economic investments in companies in the realm of nanosensors with more than 500 companies currently involved in this area (Figure ). In terms of geographical distribution, companies headquartered in the United States dominate accounting for 70% of the total capital invested and is followed by companies originating from United Kingdom (13%) (Figure inset). The United States saw an especially large influx in capital investment in 2020 -nearly 2.2 billion USD (Figure ). Distribution across industry group indicates highest degree of interest from the healthcare devices and supplies sector, unsurprisingly, accounting for half of all capital invested, followed by the pharmaceutical and biotechnological sector (Figure ). This agrees with our analysis which indicated that the largest fraction of application of nanosensors is in the biomedical and other allied fields.
