SECTION CDIAGNOSISAncient Chinese medicine held that the gallop of the pulsereflected the state of the body, and practitioners used theintricate patterns of the heartbeat to confirm many diagnoses.In the age of technology, patterns also hold clues tothe status of the organism. Two techniques used in adaptiveoptics technology, originally developed to discern wavelengthpatterns in the scattering atmosphere, can remotelydiagnose eye disorders. Vibrational spectroscopy can bothvisualize and quantify biochemical species in unstained cellsamples. Applications in both spectroscopy and luminescentmaterials have led to devices that can detect airborne contaminants,cancerous cells, bioluminescent signatures of bacteria,and specific gene sequences. Even ultraprecise gimbaltechnology derived from laser communications research hasfound a place in a needle biopsy system.1. A wavefront sensor that can process data on astigmatism,interpupil distance, and ocular accommodation andcan do so over telemedical routes.2. A deformable mirror that improves retinal imaging for thestudy of photoreceptors in the eye.3. An infrared array that is the heart of a microscope that canvisualize and quantify silicone leakage in breast tissue.4. A multispectral sensor that analyzes biological material inthree dimensions.5. A combination spectrometer-endoscope that helps doctorsdiagnose oropharyngeal cancer.6. A nonradioactive, nonfluorescent gene probe that distinguishesdouble-stranded DNA from single-stranded DNA.7. Nanocrystals that emit visible light when excited byinfrared wavelengths and have potential as molecular tags.8. A spectroscopic method that reveals true-color images ofcancerous versus normal tissue.9. A robust, extremely accurate driver for guided needlebiopsy of the breast.
