An eight channel smartphone spectrometer has been developed that can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers. Unlike current smartphone spectrometers, which are used to monitor or measure one sample at a time, the multichannel smartphone spectrometer (MSS) can optically analyze several samples simultaneously, adding to its potential value as a high-throughput device. Washington State University researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch...Read full articleRelated content from Photonics MediaARTICLESMicrofluidic Device with Fluorescent Sensor Detects EbolaA faculty-researcher at Rochester Institute of Technology (RIT) has developed a prototype microdevice with biosensors that can detect the Ebola virus.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookDetectors: CCDs for Life-Science Applications: The CCD camera is becoming the imaging method of choice in biological laboratories for its resolution, versatility and ease of use. Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookWHITEPAPERSIdentifying Thermally Activated Delayed Fluorescence using a SpectrofluorometerTADF was first observed in 1924 by Francis Perrin.
