Characterization and Sensing of Inert Gases with a High-Resolution SPR Sensor

Sensors, 2020
It is generally difficult to characterize inert gases through chemical reactions due to their inert chemical properties. The phase interference-sensing system based on high-resolution surface plasmon resonance (SPR) has an excellent refractive index ...

SPR biosensor based on polymer multi-mode optical waveguide and nanoparticle signal enhancement [PDF]

, 2020
We present a surface plasmon resonance (SPR) biosensor that is based on a planar-optical multi-mode (MM) polymer waveguide structure applied for the detection of biomolecules in the lower nano-molar (nM) range. The basic sensor shows a sensitivity of 608.

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

Advanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Chemoproteomic Identification of AKT2 as a Paclitaxel‐Binding Protein via C─C Bond‐Linked Probe PTX‐4 in Paclitaxel‐Resistant Breast Cancer

Advanced Science, EarlyView.
ABSTRACT Breast cancer remains one of the most prevalent malignancies among women, and taxane‐based chemotherapies such as paclitaxel and docetaxel are central to standard treatment regimens. However, drug resistance in breast cancer limits therapeutic efficacy and contributes to recurrence and metastasis.

Thymosin Alpha‐1 Provides Direct Neuroprotection by Engaging the Orexin Receptor HCRTR1 to Suppress Neuronal Necroptosis

Advanced Science, EarlyView.
In this study, we unveil a thymus‐brain endocrine axis wherein Tα1 engages HCRTR1 to inhibit RIPK3‐mediated necroptosis. This study nominates the Tal‐HCRTR1‐RIPK3 axis as a potent and clinically translatable therapeutic target for stroke and neurodegeneration.
