Skype co-founder Jaan Tallinn has joined the advisory board of Nanotronics Imaging, a Brooklyn-based nanotechnology start-up that develops optical microscopy tools for healthcare, biotechnology, and life sciences research.

The move suggests that the entrepreneur, who has his roots in software engineerin, is looking at the medical technology sector with an increasing interest. 

In 2012, Tallinn co-founded private medical consultancy firm MetaMed, which charges patients between $5,000 and $20,000 for its personalised medical research services. 

Nanotronics Imaging, founded in 2010, has technology that combines optical microscopy with patented image processing and machine intelligence algorithms to allow for the imaging of a large area of a specimen with nanoscale resolution. 

Nanotronics Imaging, which is based in Red Hook, Brooklyn, has been recognised by silicon insiders as the company that's going to change the way we see and build everything and impact the internet of things.

The firm recently completed a $7 million Series B financing round from Founders Fund, a San Francisco-based technology investment firm that has backed successful companies including Palantir, MetaMed, SpaceX, Facebook, ZocDoc and The Climate Corporation.

Tallinn is also the co-founder of MetaMed, a personalised medical research company, and a partner at Ambient Sound Investments. In addition, he is one of the founders for the Centre for the Study of Existential Risk at the University of Cambridge and was an advisor and member of the board of Deepmind, acquired by Google this year.

Tallinn, who told Techworld last November that Google may have been a better fit for Skype than Microsoft, said: "Nanotronics Imaging and MetaMed both represent a significant disruptive force in medicine and health: a qualitative improvement in the collection and analysis of health information.

"The entire field is undergoing a sea change with new ways to collect, monitor, and analyse bio-information becoming available. I'm looking forward to working with Matthew Putman and his team as they continue to develop new applications for the company's optical microscopy technology."

Nanotronics founder Matthew Putman said, "We are thrilled to have Jaan Tallinn join us in developing our vision for transformative technology. His global leadership in health care and technology gives him a unique perspective, and his original thinking is a priceless asset. I am honoured to have him on board."
