It based on near-infrared spectroscopy, which means it reflects light onto an object, then collects and analyzes the light reflected back.
While scientists and researchers use near-infrared spectroscopy on a regular basis, there are lots of consumers that would love to know more about the chemical composition of the world around them,
and time-resolved spectroscopy at the Center for Nanoscale Materials verified the movements of the electrons within the system,
Ultrafast terahertz spectroscopy yields direct insight into the building block of modern magnetic memories July 6th, 2015chip Technology Building the electron superhighway:
and whispering galleries are found in applications ranging from sensing, spectroscopy and communications to the generation of laser frequency combs.
The technique called quartz-enhanced photoacoustic absorption spectroscopy (QEPAS invented at Rice by Tittel, Professor Robert Curl and their collaborators in 2002,
"Raman and infrared spectroscopy are the two tools that one uses to see molecular structure, "Bhargava said."
We use spectroscopy to confirm the formulation as well as visualize the delivery of the particles and drug molecules."

Arrayat the fair, the FBH exhibits novel dual-wavelength diode lasers that are suitable for use in miniaturized, portable laser measurement systems for Raman spectroscopy applications.
The innovative diode laser chip is ideally applicable for SERDS (Shifted Excitation Raman Difference Spectroscopy), enabling to measure Raman spectra under real-world conditions even in highly fluorescent environments
Moreover, SERDS improves the detection limit by one order of magnitude compared to standard Raman spectroscopy. With these FBH tiny monolithic light sources on chip level, a compact SERDS measurement head that is only as small as a laser pointer was realized for the first time.
This device is the basis for a unique miniaturized and versatile SERDS spectroscopy system, enabling in-situ measurements in various security and health relevant fields including biology, medicine, food control, and pharmacy.
Applications in absorption spectroscopy and for generating terahertz radiation are also conceivable. Arrayfiber-coupled demonstrators newly developed at FBH for industrial use aim at integrating laser radiation with high spectral brightness into various systems
They used spectroscopy to confirm the formulation as well as visualize the delivery of the particles and drug molecules.
