Two photon excitation

Shenfeng Qiu

Dr. Shenfeng Qiu also trains new users for the Phoenix Biomedical Campus' Biomedical Imaging Core facility (confocal, and two photon microscope). His group has utilized confocal microscopy for multiple fluorophore acquisition, and also has performed in vivo imaging in mouse brain.

Biomedical Imaging Core (COM-PHX)

New techniques available on the Zeiss 880 Laser Scanning Confocal Microscopes at the UA

Roundtable discussion Wed. April 13 at noon in room 601 Gould-Simpson Building

Installation was completed in March 2016 of the campus’ new Zeiss 880 inverted microscope laser scanning confocal microscope (LSCM) and the Zeiss 880 fixed stage upright multi-photon LSCM with airyscan (a new super resolutions technique).

ORD announces the arrival of three new Zeiss optical microscopes

The Office for Research & Discovery (ORD) is pleased to announce the arrival two new state-of-the-art laser scanning confocal microscopes and a structured illumination system (SIM) in the ORD imaging facilities in January and Feb 2016.  These unique and enabling microscopes will be a huge advancement in the microscopy equipment available to researchers on campus!

Two-photon - UA Microscopy clinic (July 2014)

If you are a microscope user and have questions on how to best image your sample you might be interested in attending the first UA Microscopy Clinic. This first meeting will focus on the shared two photon intravital microscope facility in Keating. 

Deeper fluorescence imaging – an examination of clearing techniques

Many researchers would love to image deeper into fluorescently labeled, sectioned tissue without the need to use two-photon microscopy.  Deep imaging suffers from the effects of a number of optically-related artifacts.  Several recent techniques have been proposed to alter the optical properties of the sample (CLARITY, SCALE, etc) and greatly improve the ability to image deeper.  Shane Andrews (Olympus America) will review these techniques, sharing their pluses and minuses, as well as tips (including new Olympus specialty objective lenses) for success.
