Spectroscopic Method Development and Implementation

In this edition of “Inside the Laboratory,” Elise Granek of Portland State University, in Portland, Oregon, and Susanne Brander of Oregon State University, in Corvallis, Oregon, discuss their collaborative research efforts and what their laboratories are working on.

Spectroscopy recently sat down with Elise Granek, Susanne Brander, and Summer Traylor to discuss their recent study quantifying microplastics (MPs) and anthropogenic particles (APs) in the edible tissues of black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific lamprey, and pink shrimp.

Presentations held during the first half of SPIE Photonics West 2025 highlighted the latest technological advancements in spectroscopy and how they can improve quality of life for people around the world.

A team of researchers from Nankai University has developed an advanced method to classify tea types using near-infrared spectroscopy (NIRS) and artificial intelligence (AI). Their approach, involves a fine-tuned 1DResNet model, outperforms traditional methods, and offers an accurate, non-destructive, and efficient classification solution for the tea industry.
