We report a handy, simple and inexpensive paper device for extremely sensitive detection of peroxide-based explosives. The sensing device fabricated using a curcumin derivative was capable of ultrafast sensing of triacetone triperoxide. The detection time was below 5 s. Moreover, the sensor retained full function under storage at ambient temperature for at least 120 days.

Purpose: To evaluate the occurrence of complications following intravitreal injections (IVIs) performed in an outpatient clean room (OCR) equipped with the mobile laminar airflow device (LAF) Operio.
Methods: This retrospective study analyzed the data of 10,016 IVIs performed in an OCR from April 2023 to November 2024. All information of each patient was registered, such as diagnosis, drug injected and any occurring complication or adverse events such as endophthalmitis, intraocular inflammation, rhegmatogenous retinal detachment (RRD), vitreous hemorrhages and elevated intraocular pressure.

Positron emission tomography (PET) is a valuable tool for diagnosing malignant tumors. Intraoperative PET imaging is expected to allow the more accurate localization of tumors that need resections. However, conventional devices feature a large detector ring that obstructs surgical procedures, preventing their intraoperative application.

Purpose: The multi-modality imaging system offers optimal fused images for safe and precise interventions in modern clinical practices, such as computed tomography-ultrasound (CT-US) guidance for needle insertion. However, the limited dexterity and mobility of current imaging devices hinder their integration into standardized workflows and the advancement toward fully autonomous intervention systems. In this paper, we present a novel clinical setup where robotic cone beam computed tomography (CBCT) and robotic US are pre-calibrated and dynamically co-registered, enabling new clinical applications.

Accurate and rapid aflatoxin B1 (AFB1) detection is essential for ensuring the safety of food supplies. In this paper, we introduce a distance-readout paper-based microfluidic chip (DPMC) that offers a sensitive and reliable method for the detection of AFB1. The DPMC comprises a DNA hydrogel sensitive valve and a paper-based capillary channel.

We demonstrate a thermally controlled ultra-wideband wide incident angle metamaterial absorber with switchable transmission at the THz band in this paper. The underlying hybrid structure of FSS-VO thin films make them switchable between absorption mode and transmission mode by controlling the temperature. It can achieve ultra-wideband absorption with above 90% absorption from 1 THz to 10 THz and exhibits excellent absorption performance under a wide range of incident and polarization angles at a high temperature (80 °C).
