Colloidal metals and bioluminescence

Colloidal metals: past, present and future

A critical assessment of the various X-ray and electron-based methods of determining the structure of ultrafine metallic particles of colloidal dimension is given. In particular, examples of the use and potential of high-resolution electron microscopy of high-angle Rutherford scattering and of scanning tunneling microscopic procedures are illustrated. Several growth points of current and possib...

Chemical speciation and toxicity of metals assessed by three bioluminescence-based assays using marine organisms.

Metal toxicity is a function of the biology of the target organism and the chemical speciation of the metal. The toxicity of 11 metals was assessed with three cell-based bioassays based on marine organisms: the bacterium Photobacterium phosphoreum of the Microtox bioassay, an environmental strain of P. phosphoreum, and photocytes isolated from the brittlestar Ophiopsila californica. Metal speci...

Bioluminescence.

Bioluminescence

Kahle and Umbers introduce the ways by which organisms emit light though chemical reactions.

Bioluminescence

Bioluminescence is a two-person improvised performance to be considered for either concert or club performance. The performance is improvised and of variable length, and consists of a vocalist (Lesley Flanigan) and a laptop performer (R. Luke DuBois). All the material generated from the laptop is taken from the vocalist during that performance (no pre-sampling or synthesis) and the laptop perfo...
