Nanosys, a US-based technology company that makes small components for lights and batteries, has raised a further $6m to close its extended series E round after Korea-based electronics conglomerate Samsung’s corporate venturing division invested $15m in the first close in August.

The extended E round closed at $31m with the remainder coming from venture capital investors, including Arch Venture Partners, El Dorado Ventures, Polaris Venture Capital and Venrock. The company has now raised $126m in total since its launch.

Steven Goldby, partner at Venrock and chairman of Nanosys, said: "Flat panel displays are a $100bn market and lithium-ion battery market is projected to exceed $70bn by 2020. Having invested in the company since its start in 2002, we’re pleased to see its continued progress and expansion."
