UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

An Electrically Small Patch Antenna Sensor for Salt Concentration Measurement of NaCl Solution

Sensors
In this paper, a complementary split-ring resonator (CSRR)-based patch antenna is proposed as a microwave sensor to measure the salt concentration of NaCl solution. The microwave sensor consists of an RF-4 substrate, where a small copper disc is attached

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Time Series Consistency of Passive Microwave Sensors (1978–2023) Brightness Temperature Data for Snow Depth Estimation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Passive microwave remote sensing offers all-weather, all-day observations, but sensor inconsistencies hinder long-term continuity and multisensor integration for surface parameters estimation. This study proposed methods to improve brightness temperature
