Near-Infrared Spectroscopy: Delving Deeper in the Brain
Near-Infrared Spectroscopy: Delving Deeper in the Brain
As a functional brain monitoring and imaging technique, functional near-infrared spectroscopy (NIRS) has undergone a tremendous transformation. Over the past two decades, the technology has grown from bulky prototype instruments measuring one or two points on the head to sophisticated systems providing whole-brain coverage and real-time display and enabling an array of important applications, including applications in behavioral research, psychiatry, memory loss, and stroke and brain injury. In many cases, the technological developments have occurred alongside changes in the user base and the emergence of new applications, often — though by no means always — in response to those changes.

Photosynthesis Map May Hold Clue to Improving Solar Cell Efficiency
Photosynthesis Map May Hold Clue to Improving Solar Cell Efficiency
The results of measuring the flow of energy during photosynthesis using spectroscopy could contribute to the development of more efficient solar energy technologies. Researchers at Lund University used ultrafast 2D electronic spectroscopy to track the excitation-energy flow through the entire photosynthetic system of green sulfur bacteria. They located the routes along which solar energy was transported, mapped the functional organization of individual complexes within the photosynthetic unit and demonstrated that energy was transferred within subunits within a period of subpicoseconds to a few picoseconds. They additionally demonstrated that across cell components, energy was transferred within a much lengthier timeframe of tens of picoseconds.

Two-Dimensional MEMS Arrays Pave Way for Mobile Spectrometers
In the field of near-infrared (NIR) spectroscopy, a system that combines portability with the accuracy and functionality of high-performance laboratory systems would significantly enhance real-time analysis. The development of small handheld spectrometers, powered by a battery, could lead to more efficient monitoring of industrial processes or assessments of food ripeness in the field.

Holographic Imaging Technique Diagnoses Malaria Automatically, Accurately
Holographic Imaging Technique Diagnoses Malaria Automatically, Accurately
A quantitative phase spectroscopy (QPS) system that incorporates digital holography has been used to spot malaria-infected cells from a simple, untouched blood sample without any help from a human. The technique employs machine learning algorithms and has been shown accurate in detecting malaria infection 97 to 100 percent of the time. The research could form the basis of a fast, reliable test for malaria that could be given by most anyone, anywhere in the field.

Innovation in Surface Tracking Opens Doors to Raman Imaging Applications
Innovation in Surface Tracking Opens Doors to Raman Imaging Applications
Scientists dream of being able to probe variations in the chemical composition and structure of materials without any form of sample preparation. Raman spectroscopy, a noncontact, nondestructive analysis tool that yields information on the chemical, vibrational, crystal and electronic structure of materials at the submicron scale, promises this. The primary hurdle has been keeping samples in optical focus during imaging measurement.
