Cold atmospheric plasma combined with nanoparticles in cancer therapy

Interdisciplinary Medicine, EarlyView.
Cold atmospheric plasma (CAP) generates a range of reactive oxygen and nitrogen species (RONS), including singlet oxygen (1O2), hydrogen peroxide (H2O2), hydroxyl radicals (·OH), nitrate (NO3− ${{\text{NO}}_{3}}^{-}$), and nitrite (NO2− ${{\text{NO}}_{2}}^{-}$), which induce oxidative stress and apoptosis in cancer cells.

Ultrasmall Superparamagnetic Iron Oxide Nanoparticles as Positive Contrast Agents in Low‐Field Magnetic Resonance Imaging

iRADIOLOGY, EarlyView.
Ultrasmall superparamagnetic iron oxide nanoparticles emerge as promising positive contrast agents for low‐field MRI. Unlike larger SPIONs, these particles exhibit enhanced T1 relaxivity through rapid magnetic fluctuations and surface spin canting. Their biocompatibility, renal clearance pathway, and bright contrast generation offer safer alternatives ...

Analysis of the experimental absorption spectrum of the rabbit lung and identification of its components

Journal of Biophotonics, EarlyView.
The broadband absorption coefficient spectrum of the rabbit lung was reconstructed from the absorption spectra of tissue components. The similar accumulation of melanin and lipofuscin was retrieved from the broadband baseline in the absorption coefficient spectrum, and the calculation of the absorption fold ratios for proteins, DNA and hemoglobin ...

Thermo‐Optically Tunable Mid‐Infrared Bandpass Filters Comprising Ultra‐Thin Silicon‐on‐Sapphire Metasurfaces

Laser &Photonics Reviews, EarlyView.
Ultra‐thin, tunable bandpass filters are a pathway to realizing mid‐infrared spectrometers that are compact, low power, and performant. The authors elicit 141 nanometres of passband tunability in the mid‐infrared in silicon on sapphire zero‐contrast gratings by exploiting silicon's high thermo‐optic coefficient.
