Superresolution Microscopy Enhances Biomedicine
Superresolution optical microscopy — a technology that enables the acquisition of fluorescent micrographs of samples with a resolution well below the optical diffraction limit of ~250 nm — is rapidly evolving. Several methods have been developed during the past two decades that allow for this extension of conventional optical microscopy, and they have substantially contributed to the overall understanding of systems as complex as the specific arrangement of chromatin in cells during interphase, or resolving the inner structure of polymer networks in microgels.

Laser-Processed Composites Help Harvest Biofuels
Ever-increasing environmental concerns have placed biofuels in the spotlight of research and development efforts in search of a clean energy solution. In this context, microalgae biomass harvested with pulsed lasers is a viable alternative for the production of biofuels, including biodiesel, bioethanol, biogas, and biohydrogen.

Mesoscale Photonic Method Increases Range of Optical Tweezers
A team from Tomsk Polytechnic University (TPU), working with scientists from the V.E. Zuev Institute of Atmospheric Optics of the Siberian Branch of the Russian Academy of Sciences, has increased the operation range and stability of optical tweezers. In the team’s method, light, interacting with a microparticle, is focused in the form of a photon jet in the direction opposite the radiation incidence. The photon jet functions as a trap.

Lasers in Industry
Photonics Media
Photonics Media has gathered articles and other valuable resources into a guide to the current use of lasers in industry, a reference tool and a resource for learning. This book is for anyone working on, implementing or considering the application of lasers for and in industrial settings for materials processing, quality control and production.

Pulsed MIR Spectrum Analyzer
Bristol Instruments Inc.
The NEW model 772 spectrum analyzer is for pulsed lasers operating from 1 to 12 μm. It measures wavelength to an accuracy of ±10 parts per million, and bandwidth and longitudinal mode structure to a resolution of 4 GHz, providing the ideal solution for scientists and engineers who need to know the spectral properties of their pulsed mid-IR lasers.

Chemists at the University of Groningen have designed a near-infrared light-powered rotary motor, the type that can be used to deliver autonomous motion to a system, or to ensure that a system responds to a prompt on command. The chemists administered near-infrared light to their molecular motor through an antenna.

A collaboration between researchers at the University of Warsaw and the Weizmann Institute of Science yielded a method of fluorescence microscopy that, in theory, has no resolution limit. In practice, the team demonstrated a fourfold improvement over the diffraction limit.
