Multiscale Thermal Analysis of Gold Nanostars in 3D Tumor Spheroids: Integrating Cellular‐Level Photothermal Effects and Nanothermometry via X‐Ray Spectroscopy

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates nanoscale temperatures generated by photoexcited gold nanostars and their correlation with microscale thermal damage at the cellular level. Using X‐ray absorption spectroscopy and confocal microscopy in 3D cancer spheroids, it assesses localized heating effects and examines tumor cell structure and integrity, offering insights ...

Characterizing the Atmospheres of Irradiated Exoplanets at High Spectral Resolution [PDF]

open access: yesarXiv, 2019
The best-characterized exoplanets to date are planets on close-in transiting orbits around their host stars. The high level of irradiation and transiting geometry of these objects make them ideal targets for atmospheric investigations. However, the modest apertures of many current telescopes allow mostly low resolution spectra to be observed for ...

Living Microalgae‐Based Magnetic Microrobots for Calcium Overload and Photodynamic Synergetic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

Atmospheric Distribution and Escape of Odd Nitrogen on Mars

open access: yesThe Astronomical Journal
The total nitrogen budget in the Martian upper atmosphere is significantly contributed by the presence of odd nitrogen, mainly in the form of NO and ground-state or excited-state N.
