AI Article Synopsis

  • Viruses pose significant threats to global health and economies, necessitating a deeper understanding of their infectious states.
  • Current methods for studying viruses are largely inadequate, prompting the need for better techniques.
  • The new FAIRY assay can quickly distinguish between intact and nonintact enveloped viruses, showcasing its potential for studying viral infectivity and treatment applications.

Article Abstract

Viruses are a considerable threat to global health and place major burdens on economies worldwide. Manufactured viruses are also being widely used as delivery agents to treat (gene therapies) or prevent diseases (vaccines). Therefore, it is vital to study and fully understand the infectious state of viruses. Current techniques used to study viruses are often slow or nonexistent, making the development of new techniques of paramount importance. Here we present a high-throughput and robust, cell-free plate-based assay (FAIRY: Fluorescence Assay for vIRal IntegritY), capable of differentiating intact from nonintact enveloped viruses, i.e, infectious from noninfectious. Using a thiazole orange-terminated polymer, a 99% increase in fluorescence was observed between treated (heat or virucide) and nontreated. The FAIRY assay allowed for the rapid determination of the infectivity of a range of enveloped viruses, highlighting its potential as a valuable tool for the study of viruses and interventions against them.

Unlabelled: Iron deficiency anaemia (IDA) makes an individual prone to bacterial infections. The antimicrobial defence mechanism of neutrophils is orchestrated by Nicotinamide Adenine Dinucleotide Phosphate Hydrogen (NADPH) oxidative burst which is iron-dependent. The few previous studies documenting a decrease in neutrophil oxidative burst in iron-deficient children have been based mainly on the Nitro blue tetrazolium test (NBT).

Heparin (HEP) is one of the oldest anticoagulant drugs, widely used in clinical settings, particularly in surgery and dialysis machines. Despite its long history, it remains extensively employed in medical practice. This study introduces a selective and cost-effective method for the rapid detection of HEP using red-emission carbon dots (R-CDs).

An on-site, sensitive, and cost-effective method for determining aflatoxin B1 (AFB1) in rice samples is proposed, combining magnetic solid phase extraction (MSPE) and time-resolved fluorescence immunochromatography (TRFICA) techniques. Cost-effective rice husks were carbonized and combined with nanomaterials to make magnetic nanocomposites that acted as effective adsorbents in MSPE. Under optimal conditions, the entire process was completed in 15 min with a visual detection limit of 0.
