Abstract Cryptococcal meningitis is common in sub-Saharan Africa. Given the need for data a rapid, point-of-care cryptococcal antigen (CRAG) lateral flow immunochromatographic assay (LFA), we assessed diagnostic performance of cerebrospinal fluid (CSF) culture, CRAG latex agglutination, India ink microscopy, and LFA 832 HIV-infected persons with suspected during 2006–2009 (n = 299) Uganda 2010–2012 533) South had best (sensitivity 99.3%, specificity 99.1%). Culture sensitivity was dependent...
Heat beyond visual: The thermal contrast from the heating of gold nanoparticles upon laser stimulation can improve analytical sensitivity lateral flow assays (LFAs; see picture). A 32-fold improvement in an approved LFA for cryptococcal antigen (purple diamond) was shown, with potential further by optimizing backing material and properties antibody-coated (red circle blue Y).
Abstract Gold nanoparticles (GNPs) are widely used for biomedical applications due to unique optical properties, established synthesis methods, and biological compatibility. Despite important of plasmonic heating in thermal therapy, imaging, diagnostics, the lack quantification heat generation leads difficulties comparing capability new nanostructures predicting therapeutic diagnostic outcome. This study quantifies GNP by experimental measurements theoretical predictions gold nanospheres...
Zebrafish embryos can attain a stable cryogenic state by microinjection of cryoprotectants followed rapid cooling, but the massive size embryo has consistently led to failure during convective warming process. Here we address this zebrafish cryopreservation problem using gold nanorods (GNRs) assist in Specifically, microinjected cryoprotectant propylene glycol into along with GNRs, and samples were cooled at rate 90 000 °C/min liquid nitrogen. We demonstrated ability unfreeze rapidly (1.4 ×...
Carbon dioxide is the major greenhouse gas that contributes to global warming more than 60%. from power plants one of main sources. Therefore it essential reduce CO2 emission plant flue gas. Post- combustion carbon capture optimal choice in near-to meddle-term, since does not need change configuration essentially. Chemical absorption with amine-based solvents currently state-of-the-art technology for post- capture. This paper introduces typical amine process and analyses problems during...
There is an increasing need for highly sensitive and quantitative diagnostics at the point-of-care. The lateral flow immunoassay (LFA) one of most widely used point-of-care diagnostic tests; however, LFAs generally suffer from low sensitivity lack quantification. To overcome these limitations, thermal contrast amplification (TCA) a new method that based on laser excitation gold nanoparticles (GNPs), commonly visual signature, to evoke signature. facilitate clinical translation TCA...
The blood–brain barrier (BBB) is highly selective and acts as the interface between central nervous system circulation. While BBB critical for maintaining brain homeostasis, it represents a formidable challenge drug delivery. Here we synthesized gold nanoparticles (AuNPs) targeting tight junction specifically demonstrated that transcranial picosecond laser stimulation of these AuNPs post intravenous injection increases permeability. permeability change can be graded by intensity, entirely...
Abstract The treatment of glioblastoma has limited clinical progress over the past decade, partly due to lack effective drug delivery strategies across blood-brain-tumor barrier. Moreover, discrepancies between preclinical and outcomes demand a reliable translational platform that can precisely recapitulate characteristics human glioblastoma. Here we analyze intratumoral barrier heterogeneity in characterize two genetically engineered models female mice important glioma phenotypes, including...
Thermodynamic metastable nanomaterials display attractive properties due to their unique atom configuration and microstructure, distinct from counterparts found in equilibrium phase diagrams. However, fabrication remains a grand challenge because conventional methods are generally operated under near-equilibrium conditions. To break the thermodynamic limits for discovering novel materials, numerous by adopting extreme strategies have been developed, including ultrafast synthesis, Joule...
