Google unveiled plans earlier this year for a cancer-detecting wristband that it was testing using moulds of human skin . Now the firm has been awarded a patent for the technology that will 'automatically modify or destroy targets in the blood that have an adverse health effect ' . According to the files , the wearable could target these cells using an 'external energy source ' such as ultrasound or radio frequencies . Google 's patent explained its wearable ( illustrated ) could target any substances or objects that , when present in the blood , may affect the health of a wearer by transmitting energy into the vessels . This could include infrared signals , a radio-frequency or acoustic pulse , or a magnetic field . ' A number of scientific methods have been developed to examine physiological conditions of a person by detecting and measuring one or more analytes [ chemicals ] in a person 's blood , ' explained the Nanoparticle Phoresis patent . 'Analytes could ... be indicative of a medical condition or health of the person ' and could include 'enzymes , hormones , proteins , cells or other substances . ' Google continued that its wearable would target any substances or objects that , when present in the blood , may affect the health of wearer by transmitting energy into the vessels . In an interview with Bloomberg , Google Ventures ' president Bill Maris recently said he thinks it 's possible to live to 500 years old . And this will be helped by medical breakthroughs as well as a rise in biomechanics . He has already ploughed money into genetics firms and cancer diagnostic startups and said : 'We have the tools in the life sciences to achieve anything that you have the audacity to envision . I just hope to live long enough not to die . ' Mr Maris founded Google Ventures in 2009 and oversees all of the fund ’ s global activities . Elsewhere he has develop Google ’ s Calico project . Calico is a research and development company set up in 2013 by Google and Apple to tackle 'ageing and associated diseases . ' Google co-founder Larry Page said the project would focus on 'health , wellbeing and longevity ' and last September Calico partnered with AbbVie to open a research centre into neurodegeneration and cancer . This could include infrared signals , a radio-frequency or acoustic pulse , or a magnetic field . The energy used would depend on what the band is targeting , but it would be designed to alter the chemical composition of the analyte . 'In one relevant example , certain proteins have been implicated as a partial cause of Parkinson 's disease ; the development of Parkinson 's disease may be prevented or retarded by providing particles functionalized with a bioreceptor that will selectively bind to this target ' continued the files . 'These bound particles may then be used , in combination with a wearable device as described above , to modify or destroy the target protein . 'As a further example , the target could be cancer cells ; by selectively targeting and then modifying or destroying the cancer cells , the spread of cancer may be diminished . ' In January , Andrew Conrad , head of Google Life Sciences unveiled plans for a wristband which would work with nanoparticles that circulate around the body looking for cells . After travelling around the body , these nanoparticles would then be collected , using a magnet , to reveal what cells they encountered . The nanoparticles would cause the cancer cells to light up , for example , allowing the wristband to record whether there are dangerous cells in the body . The system relies on light emitted from the cells as a result of the nanoparticles , so scientists must understand how light passes through skin . So Google started making skin . It would scan the blood for so-called analytes , or chemicals , in the blood such as the presence of 'enzymes , hormones , proteins , cells or other substances . ' Google said it could target certain proteins that have been implicated as a partial cause of Parkinson 's disease , for example , or cancer cells . In January , Google 's Life Sciences lab unveiled plans for a wristband which would work with nanoparticles that circulate around the body looking for cells . To assist with their research , the scientists made moulds of human arms using both synthetic and real human skin from donors ( pictured ) To assist with their research , the scientists made moulds of human arms using both synthetic and real human skin from donors . As the wearable is still in the early stages of development , Google X is working to determine what defines a 'healthy ' person . They are monitoring 175 healthy volunteers to frequently collect physiological information . Mr Conrad admitted that people may find it 'weird ' having particles constantly tracking the cells in their body . After travelling around the body , these nanoparticles would then be collected , using a magnet , to reveal what cells they encountered . The nanoparticles would cause the cancer cells to light up , for example , allowing the wristband to record whether there are dangerous cells in the body . 'It 's way weirder to have cancer cells floating through your body that are constantly trying to kill you , ' Mr Conrad continued . He said that the Google X team is trying to change medicine from being episodic and reactive to being proactive and preventive . 'We 're making good progress but the journey is long and hard , he said . 'So I think we will get there and I hope it 's years , not decades . '
Patent details a device that could target substances in a wearer 's blood . This substances could be genetically linked with Parkinson 's , or cancer cells . It would then ' modify or destroy ' targets by transmitting signals into blood . This sensors include infrared signals , a radio - frequency or acoustic signal . Scientists in the life sciences division of Google X laboratories are using human skin in their research to modify the wristband . they could also work with pills that cause unhealthy cells to light up .
