JUNE 2004 | CONTENTSFeatures Colorful Fluorescence Stands Out in Black and Whiteby Brian Matsumoto and Ken Linberg, University of California, Santa Barbara, and Richard Crandall, OptronicsIt would seem that a color digital camera would be the best choice for multicolor analysis, but a black-and-white camera can actually offer higher spatial resolution.page 36Positioning Issues for Inverted Microscopesby Dave Denu, Ludl Electronic Products Ltd.page 40Control Technology Helps Reduce Errorsby Scott Jordan, PI (Physik Instrumente) USApage 41Stage Positioning Provides High-Speed Precision for 3-D Imagesby Dr. William O'Brien, Mad City Labs Inc.page 44Positioning Offers Imaging Optionsby James Hunt, Prior Scientific Inc.page 45Femtosecond Laser Pulses in Biology: From Microscopy to Ablation and Micromanipulationby Marco Arrigoni, Coherent Inc.Until recently, biological applications for ultrafast laser pulses were confined to sample interrogation, but now the lasers also are being used for sample manipulation.page 48ColumnsBiophotonics Research page 52Mirror, mirror, on the chip Photonic nanojets break the diffraction limit Low-cost frequency-domain fluorescence lifetime microscopy UV resonance Raman spectroscopy discriminates between bacteria species Bridging the resolution gap Dark-field illumination sheds light on chemotaxis Post Scriptsby Karen E.
