June 2023— Prof. Dennis enjoyed her trip to Vancouver to give a Keynote talk at the Canadian Chemistry Conference and Exhibition (CSC 2023).

June 2023— Welcome to Allana Souza Pereira, a visiting PhD student from Brazil!

May 2023— Congratulations to long-term Dennis Lab undergraduate researchers Artemis Margaronis and Perry Katsarakes, who graduated with their BS in Biomedical Engineering degrees from Boston University this month. We appreciate all your contributions to the lab over the years and know that you’ll both thrive in your PhD programs!

April 2023— Congratulations to Yidan and Xingjian on publication of their paper Minimizing near-infrared autofluorescence in preclinical imaging with diet and wavelength selection, published in the Journal of Biomedical Optics. This paper systematically and thoroughly demonstrates the way that we can reduce the impact of gut autofluorescence in mouse imaging by changing the diet or the excitation and emission wavelengths used for imaging. We were surprised to see autofluorescence from alfalfa-based standard chow at wavelengths as long as 1100 nm, but longer excitation wavelengths (e.g., 808 vs 670 nm) helped reduce autofluorescence, and essentially no autofluorescence was visible at wavelengths > 1250 nm regardless of what diet or excitation wavelength was used. This information will help us and others design their whole mouse imaging experiments effectively.
