A handheld luminometer with sub-attomole limit of detection for distributed applications in global health. [PDF]

PLOS Glob Public Health
Luminescence is ubiquitous in biology research and medicine. Conceptually simple, the detection of luminescence nonetheless faces technical challenges because relevant signals can exhibit exceptionally low radiant power densities.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

The plastic limit of clays [PDF]

, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Advances in nanoprobes‐based immunoassays

BMEMat
Immunoassay is a powerful technique that uses highly specific antigen‐antibody interactions to detect biochemical targets such as proteins and toxins. As a diagnostic tool, immunoassay is employed in the screening, diagnosis, and prognosis of diseases ...

Carbon Dots-Based Fluorescence Assay for the Facile and Reliable Detection of Ag⁺ in Natural Water and Serum Samples

Molecules, 2023
In this report, red-emissive carbon dots (C-dots) were facilely prepared from o-phenylenediamine via microwave-assisted hydrothermal treatment. The C-dots demonstrated excitation wavelength-independent emission with maximums at 621 nm that could be ...

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Limit of detection comparison for surface wave biosensors

, 2022
Paper 91410PBloch surface waves (BSW) propagating at the surface of truncated, one-dimensional crystals are valid candidates to improve sensors based on surface plasmon polaritons, usually referred to as surface plasmon resonance (SPR).

Sensitive, Selective and Reliable Detection of Fe³⁺ in Lake Water via Carbon Dots-Based Fluorescence Assay

Molecules, 2022
In this study, C-dots were facilely synthesized via microwave irradiation using citric acid and ethylenediamine as carbon precursors. The fluorescence emissions of the C-dots could be selectively quenched by Fe3+, and the degree of quenching was linearly
