An ultrasensitive angular interrogation metasurface sensor based on the TE mode surface lattice resonance.

Microsyst Nanoeng

January 2025

National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing, 100871, PR China.

The localized surface plasmon resonance metasurface is a research hotspot in the sensing field since it can enhance the light-matter interaction in the nanoscale, but the wavelength sensitivity is far from comparable with that of prism-coupled surface plasmon polariton (SPP). Herein, we propose and demonstrate an ultrasensitive angular interrogation sensor based on the transverse electric mode surface lattice resonance (SLR) mechanism in an all-metal metasurface. In theory, we derive the sensitivity function in detail and emphasize the refraction effect at the air-solution interface, which influences the SLR position and improves the sensitivity performance greatly in the wide-angle.

Lamivudine plus dolutegravir (3TC/DTG) and bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) regimens are commonly used as first-line treatments for people living with human immunodeficiency virus (HIV) (PLWH) worldwide. There are limited comparative data on the antiviral activity and safety between these regimens in ART-naive PLWH, particularly in China, where the 3TC/DTG regimen was integrated into first-line therapy in 2021 and gained broader adoption after its inclusion in the National Health Insurance in 2022. This study aims to provide real-world evidence comparing the 3TC/DTG regimen to the B/F/TAF regimen in ART-naive PLWH in China.

Craniofacial bone defect healing in periodontitis patients with diabetes background has long been difficult due to increased blood glucose levels which cause overproduction of reactive oxygen species (ROS) and a low pH environment. These conditions negatively affect the function of macrophages, worsen inflammation and oxidative stress, and ultimately, hinder osteoblasts' bone repair potential. In this study, we for the first time found that ANXA1 expression in macrophages was reduced in a diabetic periodontitis environment, with the activation of the NLRP3/Caspase-1/GSDMD signaling pathway, and, eventually, increased macrophage pyroptosis.
