Non-fluorescent nanoscopic monitoring of a single trapped nanoparticle via nonlinear point sources

Detection of single nanoparticles or molecules often relies on the attachment of fluorescent labels. Here, the authors demonstrate trapping a single nanoparticle on a bowtie nanoantenna and monitoring via second harmonic generation from the particle.

Label-free adaptive optics single-molecule localization microscopy for whole zebrafish

Specimen-induced aberration can limit the imaging depth in single-molecule localization microscopy (SMLM). Here, the authors apply label-free wavefront sensing adaptive optics to SMLM for deep-tissue super-resolution imaging.

Near-field sub-diffraction photolithography with an elastomeric photomask

Photolithography is an established microfabrication technique but commonly uses costly shortwavelength light sources to achieve high resolution. Here the authors use metal patterns embedded in a flexible elastomer photomask with mechanical robustness for generation of subdiffraction patterns as a cost effective near-field optical printing approach.

Integrated arrays of air-dielectric graphene transistors as transparent active-matrix pressure sensors for wide pressure ranges

Electronic skins and health monitoring devices rely on integrated tactile sensors, which often require tailored degrees of sensitivity in specific pressure ranges. Here, the authors fabricate a versatile matrix array of pressure-sensitive graphene transistors operating in the wide 250 Pa to 3 MPa pressure range.

Universal light-guiding geometry for on-chip resonators having extremely high Q-factor

High-Q resonators are used to enhance nonlinear phenomena in photonics, but developing a fabrication process to shape a new material into a resonator is challenging and costly. Here, the authors present a method using vapour deposition on pre-patterned substrates to fabricate resonators with any new material.

Detection of cracked teeth using a mechanoluminescence phosphor with a stretchable photodetector array

We demonstrate the early diagnosis of cracked tooth syndrome (CTS) by imaging the microcracks on a tooth in the closed mouth condition using a mechanoluminescence (ML) phosphor and a stretchable and self-healable photodetector array that can conformably cover a single tooth. This method does not require sophisticated equipment and hence will be useful in the early diagnosis of CTS. To the best of our knowledge, this is the first report on the use of ML for the detection of the position of tooth cracks.

Photo-patternable and transparent films using cellulose nanofibers for stretchable origami electronics

Photo-patternable and transparent cellulose hybrid films as flexible and stretchable substrates exhibit outstanding mechanical, optical and thermal properties. Exploiting the photo-patternability of the hybrid film, reversibly foldable and stretchable forms of the substrate can be produced by integrating patterns of this hybrid film with elastomeric joints. Flexible touchscreen panels and transparent organic light-emitting diodes using hybrid films are demonstrated.
