As the computation and communication circuits we build radically miniaturize (i.e. become so low power that 1 pJ is sufficient to bang out a bit of information over a wireless transceiver; become so small that 500 µm2 of thinned CMOS can hold a reasonable sensor front-end and digital engine), the barrier to introducing all sorts of interfaces and control loops into organisms will lower radically....
In this study, we investigated the gene delivery efficiency of ultrasound sonication on plasmid DNA prior to transfection. The transfection efficiencies of the normal pEGPF (concentration of 500ng/well), and the pEGPF applied ultrasound were evaluated by transfection experiment with lipofectamineTM 2000 (Invitrogen) to CT26 cell. The 4.2-kbp pEGFP-C1 (Roche Applied Science) were amplified in Escherichia...
