Bioluminescence-based ATP assays using a charge-coupled device imaging system

Bioluminescence-based ATP assays using a charge-coupled device imaging system.

The uses and abuses of rapid bioluminescence-based ATP assays.

Bioluminescence-based ATP testing of solid surfaces has become well established in the food processing industry as part of general hazard analysis and critical control points (HACCP) measures. The rise in healthcare associated infections (HAIs) at the turn of the century focussed attention on the environment as a potential reservoir of the agents responsible for such infections. In response to ...

Image Reconstruction of a Charge Coupled Device Based Optical Tomographic Instrumentation System for Particle Sizing

This research investigates the use of charge coupled device (abbreviated as CCD) linear image sensors in an optical tomographic instrumentation system used for sizing particles. The measurement system, consisting of four CCD linear image sensors are configured around an octagonal shaped flow pipe for a four projections system is explained. The four linear image sensors provide 2,048 pixel imagi...

Molecular Imaging Using Bioluminescence

Recent progress in the development of non-invasive imaging technologies continues to strengthen the role of molecular imaging in biological research. Small animal imaging with bioluminescence has been validated recently in a variety of research models and have been shown to provide continuous quantitative monitoring of the location(s), magnitude, and time-variation of gene delivery and/or expre...

Area x-ray detector based on a lens-coupled charge-coupled device

An area x-ray detector constructed using commercially available “off-the-shelf” parts is described and its performance is characterized. The detector consists of a 1024 1024 pixel charge-coupled device CCD camera optically coupled to x-ray sensitive phosphor screen using a standard 35 mm camera lens. The conversion efficiency, spatial nonuniformity, spatial resolution and the detective quantum ...
