More and more companies from outside the pharmaceutical industry are investing in this sector, having noted its huge potential for growth. The Internet giant Google recently won a patent for a connected wristband to treat cancer.

The wristband is used in conjunction with a medication taken in advance that would target cancerous cells found in the blood, latch on to them and destroy them. The technology behind the process has not yet been defined, as the research team is still looking to determine the most effective solution: infrared and acoustical impulse technologies are among the candidates.

This is hardly Google’s first venture into the pharmaceutical industry: Its teams are already developing smart contact lenses for diabetics and mapping the human genome.
