Optoacoustics, 3D Printing Form Sound Fields With Specific Shapes
A method for generating ultrasound via light, coupled with 3D printing, has demonstrated the ability to form sound fields with specific shapes, for potential use in biological cell manipulation and drug delivery. This method could provide a simpler, less expensive alternative to the use of piezoelectric arrays to produce sound waves.

Challenges and Opportunities in Superresolution
In the last 15 years, scientists have begun using superresolution microscopy techniques to image living phenomena beyond Abbe’s theoretical limit. In a relatively short time, these techniques and instruments have become popular in the study of far-ranging biological phenomena. Superresolution can be an ideal solution for biologists who need to resolve structures beyond the diffraction limit of optical microscopy, including those whose specimens are incompatible with electron or atomic force microscopy.

FLIM Delivers Intracellular Images Based on Differences
Fluorescence lifetime imaging microscopy (FLIM) enables researchers in the life sciences to get information from live specimens about interactions on the molecular scale. The technique captures the differences in the excited state decay rate from a fluorescent sample, rather than relying on the concentration of a fluorophore. Since imaging does not derive from the intensity of a signal, the technique lessens the impact of photon scattering in thick layers of sample and is generally considered more robust than intensity-based methods.

Light Sheet Microscopy (oSPIM)
Applied Scientific Instrumentation Inc.
ASI’s Oblique Single Illumination Microscope (oSPIM) is an excellent platform for high resolution light sheet microscopy for samples mounted in standard coverslip-bottom culture dishes. The oSPIM is a single-view light sheet system where the illumination light sheet is generated at an oblique angle using an oil immersion objective below the sample dish.

Perspectives in 3D Confocal Raman Imaging
Tue, May 30, 2017 11:00A EDT
This webinar, presented by WITec, will show the workflow and power of confocal Raman imaging for analyzing the chemical composition, crystallinity, stress, optoelectronic and structural properties of materials and organisms. It will introduce state-of-the-art developments in confocal Raman imaging, including user-friendly automated features and the ability to extract information from the data set more easily, leading to improved analyses. It will also cover recording surface topography of rough and uneven surfaces using WITec's TrueSurface technology. A live data evaluation of measured data sets will demonstrate the power of confocal Raman imaging today. Presenter Thomas Dieing, Ph.D., is director of applications and support at WITec GmbH in Ulm, Germany.
