Material: Institutional and public sphere, fluorescent orange paint, 350w fluorescent light, backlit film, wood, paper.
The walls and the ground are fluorescent orange. The 1925x2850x1040mm large vitrine is facing Charing Cross Road, London, WC2. It is illuminated with 350w of light. A black-white print on translucent backlit film is floating in this space. The ultra-chrome print is showing the scanned, salvaged, detonated briefcase. A box measuring 838x533x48mm is positioned right beside the window.The box contains a silk screen print. Printed in white typography on fluorescent orange background it says; “Since fluorescence in the blue-violet region is often inherent in the biological system, dyes which fluoresce in the orange, red and green regions are most usefully employed.” 
 Christie, R.M. ed., 2001. Colour Chemistry. Cambridge: The Royal Society of Chemistry, p.184. “fluorescent dyes are used extensively in the detection and identification of biological substances. Examples of such analytical applications, which most commonly have a diagnostic purpose, include the detection of specific antibodies[...] the identification of specific nucleotide sequences in DNA, the study of cell membranes and the early detection of cancer cells. The dyes are thus useful as probes for the investigation of biological activity and the mechanism of biological reactions. Research using such probes, particularly in the study of biomembrane properties, has already led to the development of new diagnostic procedures for certain diseases.
