Cross‐Platform Biosensing of Immune Receptors Using Peptide‐Functionalized Graphene

open access: yesAdvanced Science, EarlyView.
A peptide‐functionalized graphene biosensor enables sensitive and selective detection of living immune cells. Targeting Formyl‐Peptide Receptor 2 (FPR2), the assay is demonstrated on model cells and primary human neutrophils. The same assay is applied to two complementary platforms: graphene‐enhanced surface plasmon resonance for optical benchmarking ...

Origin of Shifts in the Surface Plasmon Resonance Frequencies for Au and Ag Nanoparticles

open access: yes, 2015
Origin of shifts in the surface plasmon resonance (SPR) frequency for noble metal (Au, Ag) nanoclusters are discussed in this book chapter. Spill out of electron from the Fermi surface is considered as the origin of red shift.

CD3ɛ Nanobody‐Engineered Extracellular Vesicles Driving In Vivo Generation of BiTE‐Secreting CAR‐Ts for Solid Tumor Therapy With Memory Response and Minimal Immunogenicity

open access: yesAdvanced Science, EarlyView.
HEK‐293T‐derived CD3ε Nb‐engineered EVs to generate dual‐targeting CAR‐T cells directly in vivo. These EVs selectively deliver CAR.BiTE transgenes into T cells and reprogramed to HLA‐G/PD‐L1‐targeting effector cells with enhanced memory and persistence.

Diabetes Mellitus Facilitates Gallstone Formation Through CXCR2‐NETs–Mediated Liver‐Bile Barrier Damage

open access: yesAdvanced Science, EarlyView.
Diabetes is an independent risk factor for gallstones. It upregulates CXCR2 expression in hepatic neutrophils, stimulating the formation of NETs that disrupt hepatocellular tight junctions and the liver‐bile barrier. NETs enter bile to accelerate gallstone development, while sarcosine inhibits CXCR2 and NETs production, effectively reducing diabetes ...

Magnetic Nanoparticles Functionalized Few-Mode-Fiber-Based Plasmonic Vector Magnetometer

open access: yesNanomaterials, 2019
In this work, we demonstrate a highly-sensitive vector magnetometer based on a few-mode-fiber-based surface plasmon resonance (SPR) sensor functionalized by magnetic nanoparticles (MNPs) in liquid.

ZBTB21 Is a Dual Suppressor of Pyroptosis and MHC‐I Antigen Presentation That Promotes Tumor Immune Evasion

open access: yesAdvanced Science, EarlyView.
ZBTB21 is a transcription factor that epigenetically suppresses pyroptosis and MHC‐I antigen presentation, enabling tumor immune evasion. Genetic ablation of ZBTB21 activates pyroptotic cell death and enhances antigen presentation, recruiting CD8+ T cells to overcome immune checkpoint blockade resistance.

'Spillout' effect in gold nanoclusters embedded in c-Al2O3(0001) matrix

open access: yes, 2004
Gold nanoclusters are grown by 1.8 MeV Au^\sup{2+} implantation on c-Al\sub{2}O\sub{3}(0001)substrate and subsequent air annealing at temperatures 1273K.

Label‐Free and Immobilization‐Free Protein‐Binding Assays by Ultraviolet Transient Absorption Microscopy

open access: yesAdvanced Science, EarlyView.
A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...

Design and Optimization of an Opened Suspended Core Fiber-Based SPR Sensor with Gold Cylinder Structures

open access: yesApplied Sciences, 2018
In this study, an opened three-hole suspended core fiber surface plasmon resonance sensor structure based on the combination of photonic crystal fiber and surface plasmon resonance (SPR) mechanism was proposed and analyzed. One hole in the clad layer was
