Time‐Multiplexed Organic Electrochemical Transistor for Saliva‐Based Rapid Detection of Viral Proteins

Advanced Science, EarlyView.
A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Recent Progress in Optical‐Resonance‐Assisted Movement Control of Nanomotors

Advanced Intelligent Systems, 2020
Light exerts force or torque on objects through the momentum or angular momentum exchange between photons and the objects. For absorbing structures, light also induces a thermal gradient that can be used to power the object movement.

NAT10‐Mediated ac4C Modification of circANKRD12 Reprograms the Tumor Microenvironment

Advanced Science, EarlyView.
NAT10‐dependent acetylation of circANKRD12 drives translation of the circANKRD12_354aa protein, which binds HDAC2 to stabilize c‐Myc via deubiquitination, promoting multiple myeloma (MM) cell proliferation. Concurrently, the circANKRD12‐HDAC2 axis suppresses H3ac‐mediated transcription of IFN‐γ, TNF‐α, and GZMB in NK cells, leading to NK cell ...

Numerical Study of Thermophoresis on Mass Transfer from Natural Convection Flow over a Vertical Porous Medium with Variable Wall Heat Fluxes

Applied Sciences, 2021
This study investigates heat and mass transfer under natural convection flow along a vertical permeable surface with variable wall heat fluxes through a porous medium. The non-Darcian model is employed for the medium.

AI‐Designed Cyclic Peptides Enable Controllable Modulation of the CD28 Immune Checkpoint

Advanced Science, EarlyView.
AI‐designed cyclic peptides enable controllable modulation of the CD28 immune checkpoint through reversible disruption of CD28‐CD80/CD86 interactions. The lead peptide, CIP‐3, suppresses T‐cell activation without intrinsic agonist activity, demonstrates dose‐dependent efficacy in a murine colitis model, and attenuates inflammatory cytokine production ...

Thermophoresis: moving particles with thermal gradients

, 2008
Thermophoresis is particle motion induced by thermal gradients. Akin to other nonequilibriumtransport processes such as thermal diffusion in fluid mixtures, it is both experimentally andtheoretically a challenging subject.

Thermophoretic tweezers for single nanoparticle manipulation

Beilstein Journal of Nanotechnology, 2020
We present the trapping and manipulation of a single nano-object in an aqueous medium by optically induced temporally varying temperature gradients. By real-time object tracking and control of the position of the heating laser focus, we can precisely ...

CCT2 Promotes Prostate Cancer Progression Through EIF3F‐Dependent Stabilization of FASN

Advanced Science, EarlyView.
ABSTRACT Prostate cancer (PCa) is increasingly recognized to be driven by dysregulated lipid metabolism. Although fatty acid synthase (FASN) is highly expressed in PCa, the mechanisms governing FASN protein stability and its functional integration into oncogenic lipid metabolism remain poorly defined.

Buoyancy Effects on MHD Transport of Nanofluid Over a Stretching Surface With Variable Viscosity

IEEE Access, 2019
In this mathematical study, the time-independent, incompressible, magneto-hydrodynamic nanofluid flow over a vertical stretching surface has been investigated. The impact of gravitational body forces along with convective boundary condition has also been
