Using ” nanoexplosiones ” chemicals that make small holes in the protective membrane of the cells, researchers have demonstrated a new technique to deliver therapeutic small molecules , proteins and DNA directly in living cells.
activated carbon nanoparticles by laser light trigger bursts of small explosions that open holes in cell membranes allow sufficient time for therapeutic agents contained in the surrounding liquid.
By adjusting the laser exposure, the researchers administered a small molecular marker consisting of 90 per cent of specific cells , holding over 90 percent of living cells.
Drug delivery with this technique could be particularly attractive for gene therapy , which has successfully used viruses to insert genetic material into cells – but with side effects. It could also be used for more targeted delivery of chemotherapy agents.
