chip for function, cell for transport

if a biological cell is about 10 micrometers, 

then a micrometer sized chip with nanometer transistors could be injected to that biological cell 

and that cell could move by itself to location, 

biological could be enticed to move by luring it with chemicals, 

biological cell could be modified 

micrometer sized chips with nanometer transistors manufatured by semiconductor fabrication plant 

growing biological cells in petri dish, 

robot arm with injector autonomously injecting every biological cell with one micrometer sized chip with nanometer transistors, 

then biological cells ready to be injected into specific areas of body 

when biological cell die, 

then chip stays on location
