PHOTOBIOLOGICAL
SCIENCES
ONLINE
Photobiology is broadly defined to include all biological phenomena involving non-ionizing radiation. It is recognized that photobiological responses are the result of chemical and/or physical changes induced in biological systems by non-ionizing radiation. (Constitution of the American Society for Photobiology)
The goals of photobiology are:
(1) To understand the basic mechanisms of photobiology;
this knowledge can then be used to:
(2) Develop ways to control the beneficial effects of light upon our environment;
(3) Promote ways to protect against the detrimental effects of light on biological organisms, including humans; and
(4) Develop photochemical tools and techniques for use in research, medicine,
and industry.
Photobiological Sciences Online will continue to grow as new modules are added. Your suggestions for new modules, and your comments on the existing modules, and on this web page are most welcome.
If you use these modules in a class, please let the Editor know, where, when,
and how many students, and what modules were used.
