The initial studies of highly scattering biological materials by optical means were made by
David Keilin and EF Hartree 1, 2. Using the microspectroscope they observed that the …

This book is formulated from a number of presentations made at a one-day workshop on the
subject of Photon Migration in Tissues. The meeting was held in Philadelphia at the …

Rapid and sensitive detection of optical signals from biological materials has been very
useful in studies of cell physiology and biochemistry. A rapid-scanning spectrophotometer is …

The design of a scanning and integrating microspectrophotometer for studying the
absorption of tissue cells in the wavelength region 2200 to 7000 A is described. The …

IN the ultra-microspectrophotometer for high resolution the absorption spectra of biological
objects can be determined by utilizing the entire resolving power of the microscope. In order …

Light scattered from a microscopic object and thereby lost from an imageforming system can
be one of the major sources of error in a microspectrophotometric measurement. The …

SINCE Caspersson's pioneer work in the field of microspectroscopy, several complex
electrical and optical instruments have been devised in order to study the absorption of …

A photographic method of microspectrography applicable to living cells is described.
Absorption spectra and the total amounts of absorbing substance in living chick fibroblast …

THIS communication describes the use of a simple microspectroscopic method which
