Bio-optics is challenging optical engineers, optical software developers, and medical and molecular scientists to find technological advances that will result in applications that contribute to a healthier world. New design software is helping them meet that challenge.Michael Stevenson, Breault Research Organization Inc., and Steven R. Auger, bioDevice PartnersThe fields of genomics and drug discovery would not exist as we know them without the optical systems that enable DNA sequencers, gel imagers, polymerase chain reaction machines, microarray imagers and microfluidics systems to produce the data that are leading to the next generation of medical breakthroughs. Optical technologies enable surgical devices, imaging systems, cancer detection and treatment systems, lab-on-a-chip devices for clinical diagnostics, patient care devices such as glucose monitors and a growing number of other devices. Optical components also are used in bioterrorism...Read full articleRelated content from Photonics MediaArticlesQuantitative Phase Imaging Advances Regenerative MedicineRegenerative medicine is defined as the process of replacing, engineering, or regenerating human or animal cells, tissues, or organs to restore or establish their normal function.
