MIXTURE

The specific mosquito-like object pictured above is, as far as we know, just a CGI mock-up of a conceptual design for a MAV, not a photograph of an actual working device. And although taking DNA samples or inserting micro-RFID tracking devices under the skin of people are MAV applications that may some day be possible, such possibilities currently appear to be speculative fiction rather than reality.
