These microscopic pits, which represent binary zeroes or types based on their size, are etched in concentric tracks circling the midpoint from the internal to the outer advantage of a CD. ‘It really is these pits which we transform into miniature check tubes,’ Nolte stated. ‘Each pit can take a trace level of a chemical substance that reacts to a particular protein within the blood.’ Bloodstream contains a lot more than 10,000 proteins that physicians wish to monitor, and Nolte stated up to 10,000 tracks on a CD could possibly be paired up with a different proteins. ‘Each band of pits, or ‘monitor,’ on the CD could possibly be covered with a different proteins,’ he said. Rather than seeing digital data, the laser beam reader would observe how concentrated a given proteins experienced become on each monitor. Continue reading
