Blood groups, nanorobots, and nanomedicine

Posted By: Peter D'Adamo

PREDICTION: By 2015 people (like me, hopefully) will be designing and programming nanorobots (artificially created micro-organisms) that will use the external blood group conformations as determination of self versus non-self.

Which is just in time, as I am getting a bit bored with Java and Perl.

As Robert A. Freitas writes in Nanomedicine:

"Assuming a ~(300 nm)2 chemotactic sensor pad, a nanorobot searching for a particular set of ~30 blood group antigens (Nspec = 30) requires t meas ~ 0.03 seconds to make the self/nonself determination for a particular red cell membrane it has encountered. A nanorobot seeking to determine the complete blood group type of the membrane (e.g., in mapping mode) must in the worst case search all 254 known blood antigen types (Nspec = 254), requiring at most t meas ~ 2 seconds."

Interestingly, Frietas felt that the constellation of blood group antigens was a more reliable measure of individuality (versus simply 'self') than the Major Histocompability Complex (MHC) of the Human Leukocyte Antigens (HLA).

Most researchers see these as tiny devices that would remain in holding patterns until the doctor directed their onboard computers to go to the point where they would drop their payloads, probably a real nasty lectin, like ricin. The nanobots would communicate with the outside world by acoustic messaging using ultrasound. The only physical change you will see in the patient is that he or she will very rapidly become well again. Unlike others, I don't see the robots in any sort microscopic R2D2 configuration (too difficult) but rather as of monster conglomerations made of cleavable enzymes matrixed to simple sugars bonded with fats (as glycophorins and globo-proteins) that are activated by changes in bio-impedance (zeta potential) rather than ultrasound.

Off to Vancouver.
