In Planta Microsphere-Based Lateral Flow Leaf Biosensor in Maize

SLAS Technology, 2015
Low-cost and quick detection of biotic stresses is critically important for protection of staple food crops such as maize in smallholder farms in developing countries, where access to improved seed varieties, fertilizers, and pesticides is limited due to financial and geographical reasons.

Fluorescent carbon nanoparticle-based lateral flow biosensor for ultrasensitive detection of DNA. [PDF]

Biosens Bioelectron, 2017
We report a fluorescent carbon nanoparticle (FCN)-based lateral flow biosensor for ultrasensitive detection of DNA. Fluorescent carbon nanoparticle with a diameter of around 15nm was used as a tag to label a detection DNA probe, which was complementary with the part of target DNA. A capture DNA probe was immobilized on the test zone of the lateral flow

Release of ATP in the ventral medulla during hypoxia in rats: role in hypoxic ventilatory response [PDF]

, 2005
P2X2 receptor subunits of the ATP-gated ion channels are expressed by physiologically identified respiratory neurons in the ventral respiratory column, implicating ATP in the control of respiratory activity.

Biosensors and lateral flow immunoassays: Current state and future prospects

Clinica Chimica Acta
The advent of paper-based biosensors represents a novel paradigm in point-of-care (POC) diagnostics, emerging as versatile tools. However, the broad term "biosensors" can be misleading, encompassing a range of techniques such as dipstick assays, electrochemical, microfluidics and immunoassay-based biosensors (including lateral flow (LFA), vertical flow

High-Speed Lateral Flow Strategy for a Fast Biosensing with an Improved Selectivity and Binding Affinity

Sensors, 2018
We report a high-speed lateral flow strategy for a fast biosensing with an improved selectivity and binding affinity even under harsh conditions. In this strategy, biosensors were fixed at a location away from the center of a round shape disk, and the ...
