Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

[Analysis of renal blood flow velocity in hydronephrosis].

Nihon Jinzo Gakkai shi, 1997
We investigated the velocity of renal blood flow on hydronephrosis using the pulse color Doppler ultrasound technique, comparing velocity on the healthy side with the diseased side of the renal, segmental and interlobar arteries. The velocities of the diseased side were markedly decreased, depending on the degree of hydronephrosis.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Effects of physical determinants in an unsteady blood flow in a stenosed artery

Songklanakarin Journal of Science and Technology (SJST)
This article presents a mathematical model for the impact of physical determinants in unsteady flow of blood in an artery that has stenosis. Continuity and momentum nonlinear partial differential equations (PDEs) are obtained with consideration that ...
