Overcoming the Nyquist Limit in Molecular Hyperspectral Imaging by Reinforcement Learning

Advanced Intelligent Discovery, EarlyView.
Explorative spectral acquisition guide automatically selects informative spectral bands to optimize downstream tasks, outperforming full‐spectrum acquisition. The selected hyperspectral data are used for tasks such as unmixing and segmentation. BandOptiNet encodes selection states and outputs optimal bands to guide spectral acquisition. Recent advances

Miniaturized Near-Infrared Analyzer for Quantitative Detection of Trace Water in Ethylene Glycol

Applied Sciences
To address the limitations of a traditional Fourier-transform infrared (FTIR) spectrometer, including its bulky size, high cost, and unsuitability for on-site industrial detection, this study developed a Fourier-transform near-infrared (FT-NIR ...

Distinction between clouds and ice/snow covered surfaces in the identification of cloud-free observations using SCIAMACHY PMDs [PDF]

Atmospheric Chemistry and Physics, 2005
SCIAMACHY on ENVISAT allows measurement of different trace gases including those most abundant in the troposphere (e.g. CO2, NO2, CH4, BrO, SO2). However, clouds in the observed scenes can severely hinder the observation of tropospheric gases. Several

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

BMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

Bacterial backpacks for targeted delivery of piezoelectric nanoparticles to enhance sonodynamic immunotherapy

BMEMat, EarlyView.
Leveraging bacterial hypoxia targeting, KBTO NPs accumulate at the tumor site. Under the ultrasound irradiation, KBTO NPs produce reactive oxygen species to kill tumor cells and eliminate bacteria, preventing overgrowth and inflammation. The lysed bacteria act as antigens to trigger antitumor immunity and further enhanced by the immune checkpoint ...

SIM‐CaliRam: A workflow combining simulation‐informed references and biomass‐augmented features for in‐line Raman calibration of Saccharomyces cerevisiae

Biotechnology Progress, EarlyView.
SIM‐CaliRam combines simulation‐informed references and biomass‐augmented features for in‐line Raman calibration under sparse labels and biomass‐induced spectral confounding. Run‐wise calibration and validation enable prediction of biomass, glucose, ammonium, and phosphate on an unseen S. cerevisiae fed‐batch fermentation.
