Anisotropic Sensing Performance in a High-Sensitivity Surface Plasmon Resonance Sensor Based on Few-Layer Black Phosphorus.

Few-layer black phosphorus (FLBP) is a highly promising material for high sensitivity label-free surface plasmon resonance (SPR) sensors due to its exceptional electrical, optical, and mechanical properties. FLBP exhibits inherent anisotropy with different refractive indices along its two main crystal orientations, the zigzag and armchair axes. However, this anisotropic property is often overlooked in FLBP-based sensors.

Lossy Mode Resonance Sensors Based on Anisotropic Few-Layer Black Phosphorus.

Lossy mode resonance (LMR) sensors offer a promising avenue to surpass the constraints of conventional surface plasmon resonance (SPR) sensors by delivering enhanced label-free detection capabilities. A notable edge of LMR over SPR is its excitation potential by both transverse electric (TE) and transverse magnetic (TM) polarized light. Yet this merit remains underexplored due to challenges to achieving high sensing performance under both TM and TE polarization within a singular LMR model.

[Safety and efficacy on cerebral protection with filter devices during carotid artery stenting in Chinese patients].

Objective: To assess the efficacy, safety, procedural success and long-term clinical outcome in patients underwent percutaneous carotid stenting with distal device.

Methods: Percutaneous carotid stents with distal device were implanted to 58 patients with 59 significant (> 75%) carotid artery stenosis (49 men, mean age 68 years) between January 2000 to December 2005. Forty-five out of 58 patients were symptomatic, 35 had coronary artery diseases and 10 had previous strokes.

Safety and efficacy of carotid artery stenting.

Objective: To evaluate the safety and efficacy of carotid artery stenting (CAS).

Methods: We prospectively evaluated the safety and efficacy of 76 carotid artery stenting (CAS) procedures in a consecutive series of 70 Chinese patients. This series represented a high-risk group that included patients with unstable angina, previous ipsilateral CEA, contralateral carotid artery occlusion, post-radiation carotid artery stenosis and other severe co-morbid conditions.
