Background: Laparoscopic surgery training is a demanding process requiring technical and nontechnical skills. Surgical training has evolved from traditional approaches to the use of immersive digital technologies such as virtual, augmented, and mixed reality. These technologies are now integral to laparoscopic surgery training.

In this context, we propose a straightforward approach, integrating a dynamic link library (DLL) containing all position-dependent spectral properties of the LVF into a commercial optical design software. Exemplary investigations are conducted for an LVF with a detection range of 450-850 nm.

On the heels of the continuous development of optical fiber sensing technology, optical fiber sensors based on surface plasmon resonance (SPR) have attracted widespread attention. Herein, an SPR sensor based on the six nested anti-resonant fiber (ARF) is designed and analyzed by the finite element method (FEM). All the structural parameters are optimized to achieve high-sensitivity liquid refractive index detection.

In this study, a sensitive diagnosis and spontaneously photocatalytic therapy of cancer based on chemiluminescence (CL) and nanozyme was studied. Briefly, carbon nitride-supported copper nanoparticles (CuCNs) loaded with luminol (CuCN-L) were utilized to develop a microneedle patch (CuCN-L/MN). The CuCN-L probe could target overexpressed HO in the TME and actively emit CL to achieve cancer cell imaging for diagnosis.

Vanadium oxide (VO) is an exotic phase-change material with diverse applications ranging from thermochromic smart windows to thermal sensors, neuromorphic computing, and tunable metasurfaces. Nonetheless, the mechanism responsible for its metal-insulator phase transition remains a subject of vigorous debate. Here, we investigate the ultrafast dynamics of the photoinduced phase transition in VO under low perturbation conditions.
