Simultaneous multi-signal quantification for highly precise serodiagnosis utilizing a rationally constructed platform

Nature Communications, 2019
Single channel detection methods often suffer from false positives when analysing biological samples. Here, the authors report on the development of a three-channel detection device for measuring hydrogen sulphide in serum and demonstrate application in ...

Impact of Atomic Layer Deposition to NanoPhotonic Structures and Devices: A Review

Frontiers in Materials, 2014
We review the significance of optical thin films by Atomic Layer Deposition (ALD) method to fabricate nanophotonic devices and structures. ALD is a versatile technique to deposit functional coatings on reactive surfaces with conformal growth of compound ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

HCl-gas etching behavior of (001) β-Ga2O3 under oxygen supply

Science and Technology of Advanced Materials
The planar and lateral HCl-gas etching behavior of (001) β-Ga2O3 under oxygen supply were investigated at partial pressures of P0(O2) = 0–2.5 kPa and 645–1038°C, while maintaining a constant HCl supply partial pressure of P0(HCl) at 63 Pa.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Fabrication of β-Ga2O3/air-gap structures on (001) β-Ga2O3 using HCl gas etching

Science and Technology of Advanced Materials: Methods
β-Ga2O3/air-gap structures were fabricated on (001) substrates via crystallographic etching with HCl gas. Etching at 650 °C under an HCl partial pressure of 250 Pa resulted in a vertical etch rate of 0.10 μm/min on the (001) plane and a lateral etch rate

A Tale of Two Tantalum Borides as Potential Saturable Absorbers for Q-Switched Fiber Lasers

IEEE Photonics Journal, 2019
In this paper, we analyze the performance of two tantalum-based boride (TaB and $TaB_{2}$) microparticles as potential saturable absorbers for high-power fiber lasers.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

HCl-based halide vapor phase epitaxy and selective-area HCl gas etching of (−112) β-Ga2O3

Science and Technology of Advanced Materials
We propose (−112) and crystallographically equivalent (1−1−2), (−1−12), and (11−2) planes as the fundamental crystal orientations for β-Ga2O3studies.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
