A Skoltech research team made a systematic review of publications on in vitro biocompatibility of carbon nanotubes and identified the manufacturing parameters that could make them safe for living organisms. The scientists selected about 200 papers published over the past 20 years and performed a statistical analysis of the reported research. It turned out that carbon nanotubes used as substrates are safe for living cells and, therefore, could be used for wearable, implantable and textile electronics. The paper featuring the team's findings was published in the journal RSC Advances.
