Cancer treatment has yet to fully benefit from the targeted delivery to tumors of drugs in microdevices with local nanoscale interactions. Likewise cancer monitoring and surgery would benefit enormously from miniaturized sensor or other diagnostics systems that could be used in the pre- peri- and postoperative environment. The Prospects for Life Extension Any quantitative discussion on the prospects for life extension through nanobiotechnology intervention in disease must be purely hypothetical at this stage. However speculating across the human-organ-cell-molecule model may give some idea of the possible times to application of some of the approaches under development. Table summarizes what is a very personal view of the likely outcome of convergence in NBIC. Table Some Potential Gains in Life Extension from NBIC convergence Level of Intervention Key Advance Timescale Life Extension Human Noninvasive diagnostics 5-10 years Lifesaving for some conditions Cognitive assist devices 15-20 years Higher quality of life for several years Targeted cancer therapies 5-10 years Reduction in cancer deaths by up to 30 Organ Artificial heart 0-5 years 2-3 years awaiting transplant Neural stimulation or cell function replacement 5-20 years 10-20 years extra if successful for neurodegenerative patients Cell Improved cell-materials interactions 0-15 years Lowering of death rates on invasive surgery by 10 and extending life of surgical implants to patient s lifetime Genetic therapies 30 years Gains in the fight against cancer and hereditary diseases Stem cells 5-10 years Tissue brain repair Life extension of 10-20 years Molecule Localized drug delivery 0-10 years Extending life through efficient drug targeting Genetic interventions 0-30 years Life extension by .
