Ff-nano, Short Functionalized Nanorods Derived from Ff (f1, fd or M13) Filamentous Bacteriophage

Frontiers in Microbiology, 2015
F-specific filamentous phage of Escherichia coli (Ff: f1, M13 or fd) are long thin filaments (860 nm x 6 nm). They have been a major workhorse in display technologies and bionanotechnology; however, some applications are limited by the high length-to ...

Multiplex Point-of-Care Tests for the Determination of Antibodies after Acellular Pertussis Vaccination

Diagnostics, 2020
Most of the current serological diagnosis of pertussis is based on pertussis toxin (PT) IgG antibodies and does not differentiate between vaccination and infection-induced antibodies. PT is included in all of acellular pertussis vaccines available in the

Pressed Lateral Flow Assay Strips for Flow Delay-Induced Signal Enhancement in Lateral Flow Assay Strips

BioChip Journal, 2022
This paper proposes that the signal intensity of a lateral flow assay (LFA) strip can be increased by pressing the top of the strip, effectively reducing its flow rate. The reduced flow rate allows more time for antigen-antibody interactions to occur, resulting in increased signal intensity and an improved detection limit.

Improvement of Electrochemical Trepanning by Using a Pictographic Insulation Sleeve

International Journal of Electrochemical Science, 2017
Electrochemical trepanning is an economical approach for machining straight blades made of hard to cut materials. However, the stray corrosion caused by cathode tip in traditional electrochemical trepanning process, may introduce a tapered wall of ...

Enhanced Performance of Methamphetamine Lateral Flow Cassettes Using an Electronic Lateral Flow Reader [PDF]

Journal of Occupational and Environmental Hygiene, 2014
Surface contamination from methamphetamine in meth labs continues to be a problem. We had previously developed a lateral flow assay cassette for field detection of methamphetamine contamination that is commercially available and has been used by a number of groups to assess contamination.

Clinical performance of a point‐of‐care Coccidioides antibody test in dogs

Journal of Veterinary Internal Medicine, 2021
Background Point‐of‐care (POC) Coccidioides antibody assays may provide veterinarians with rapid and accurate diagnostic information. Objectives To determine the agreement of a POC lateral flow assay (LFA), sona Coccidioides (IMMY, Norman, Oklahoma) with

Integrating a Water Tracer Model Into WRF‐Hydro for Characterizing the Effect of Lateral Flow in Hydrologic Simulations

Water Resources Research
Most current land models approximate terrestrial hydrological processes as one‐dimensional vertical flow, neglecting lateral water movement from ridges to valleys.

Rapid Detection of Alpha-Fetoprotein (AFP) with Lateral Flow Aptasensor

Molecules
We present a lateral flow aptasensor for the visual detection of alpha-fetoprotein (AFP) in human serum. Leveraging the precise molecular recognition capabilities of aptamers and the distinct optical features of gold nanoparticles, a model system ...
