Chinese tech giant Baidu is in talks with investors to raise up to $2 billion (Dh7.34bn) over three years for a biotech startup, which will use AI technology to discover new drugs and diagnose diseases, according to sources. Baidu is unlikely to be the controlling investor, one source said. More details on the investment were not avaiable as talks were still under way. Baidu's plans come at a time of increased investment in the healthcare sector since the outbreak of the Covid-19 pandemic, with many companies expanding into online diagnosis options to fill the gaps left by overstretched, overcrowded hospitals. WeDoctor, backed by Tencent, Alibaba's healthcare arm and Ping An Good Doctor have joined the fray to develop apps that offer diagnosis, prescriptions, appointment bookings, one-hour drug delivery and insurance. But the startup under discussion plans to focus more on such areas as drug discovery and development, and early tumour diagnosis, by mobilising Baidu's powerful artificial intelligence (AI) technology that can perform complex computing to produce biological innovations, sources said. The name of the startup has not been decided, but Baidu came up with the idea as early as six months ago, one source said, adding that Baidu founder and chairman Robin Li has been personally involved in the project. Baidu declined to comment. Baidu open-sourced its Ribonucleic acid (RNA) prediction algorithm LinearFold this year. The tool aims to accelerate the prediction time of a virus's RNA secondary structure, which is crucial to understand it and developing vaccines. The healthcare industry, especially biotechnology, has seen a flood of money flow in amid the scramble for a Covid-19 vaccine and governments seeking to fix their health systems. The Hang Seng Healthcare Index has surged about 40 per cent over the past five months, outstripping the Hang Seng Index that edged up more than 6 per cent over the same time.
