Short-wave infrared photothermal microscopy enables deep-tissue vibrational imaging at millimetre depth with high sensitivity and sub-cellular spatial resolution, offering potential for applications in biological and medical fields.

The propargyl radical (C₃H₃) self-reaction is a pivotal step in the formation of benzene in nature, but experimental validation for the complex reaction channels and products is challenging to obtain. Here, the authors produce propargyl radicals in a flow tube and report the branching ratios of eight identified C₆H₆ isomers in the propargyl self-reaction using isomer-selective threshold-photoelectron spectroscopy.

Second near-infrared (NIR-II) fluorescence imaging is promising for real-time surveillance of surgical operations, but its clinical uses have been limited by the safety and cost concerns associated with lasers or X-rays. Here the authors report the engineering and applications of white-light activatable organic nanomaterials with bright NIR-II emission.

To determine the physiologically relevant oligomeric form of membrane proteins is extremely challenging. Now an elegant method of counting the oligomers in membrane proteins in near-native states is presented, using photobleaching and nanodiscs formed directly from cellular membranes.

Hyperspectral imaging can reveal important information without the need for staining. To extract information from this extensive data, however, new methods are needed that can interpret the spatial and spectral patterns present in the images.

Bio-othogonal chemistry lets us determine the fate of a lignin monomer using a radical tag and EPR spectroscopy.

Overcoming the challenges of plastic detection in plants has made it possible to transfer many of the lessons learned from plant–metal nanoparticle interactions to plastic nanoparticles.
