Sensing strategies for early diagnosis of cancer by swarm of nanorobots: An evidential paradigm

Abstract

Precancerous states are necessarily characterized by the simultaneous and persistent occurrence of high temperature, high concentration of pyruvic and lactic acids and low pH. These physico-chemical features may thus be viewed as the fingerprint of a growing tumour. A detection strategy based on the use of swarm of nanorobots circulating in the haematic stream is described, together with the basic idea allowing the implementation of the sensing and actuating tools necessary to perform the job.
