Sanford A. Asher, a Distinguished Professor of Chemistry at the University of Pittsburgh (Pittsburgh, Pennsylvania), was presented with the Pittsburgh Analytical Chemistry Award on March 8 at Pittcon 2016 in Atlanta, Georgia.
Asher pioneered the development of deep ultraviolet resonance spectroscopy for use in biophysical, physical, and analytical chemistry. His group developed both instrumentation and methodologies for determining protein structure and protein folding. Among the projects Asher and his group have in the works are the development of standoff instruments for the detection of explosive molecules, and the development of novel photonic crystal optical devices and responsive materials.
Asher received his PhD in chemistry from the University of California, Berkeley, and was a postdoctoral fellow at Harvard University (Cambridge, Massachusetts) in applied physics. He is the author of more than 290 publications and holds more than 29 patents in the area of photonic crystals.
New Fluorescence Model Enhances Aflatoxin Detection in Vegetable Oils
March 12th 2025A research team from Nanjing University of Finance and Economics has developed a new analytical model using fluorescence spectroscopy and neural networks to improve the detection of aflatoxin B1 (AFB1) in vegetable oils. The model effectively restores AFB1’s intrinsic fluorescence by accounting for absorption and scattering interferences from oil matrices, enhancing the accuracy and efficiency for food safety testing.
New Study Shows FT-MIR Spectroscopy Can Authenticate Parmigiano Reggiano Farming Practices
March 11th 2025A new study published in the Journal of Dairy Science demonstrates that FT-MIR spectroscopy can effectively authenticate farming practices and dairy systems in Parmigiano Reggiano production but has limited ability to verify animal welfare parameters.
Advancing NIR and Imaging Spectroscopy in Food and Bioanalysis
March 11th 2025Our full-length interview with Huck covers more than just NIR spectroscopy in food and bio analysis. Spectroscopy sat down with Huck to also discuss current trends going on in spectroscopy, delving into what challenges spectroscopists face today and how they can solve these concerns.
The State of Forensic Science: Previewing an Upcoming AAFS Video Series
March 10th 2025Here, we provide a preview of our upcoming multi-day video series that will focus on recapping the American Academy of Forensic Sciences Conference, as well as documenting the current state of the forensic science industry.
