    Detecting clinically relevant diagnostic biomarkers, suitable for point-of-care detection, may facilitate rapid treatment and prevention of disease. However, medical diagnosis for which there are limited quantities of testable tissue or fluid, require point-of-care technologies with superior sensitivity and specificity. The purpose of this Editorial is to provide an overview of the Collection’s content, comprising original research into fluidics-based diagnostic platforms—specifically those made of paper or other low-cost materials, that can suitably operate with tiny sample volumes from mL to nL. In particular, we will focus on the clinical applications of such research, with potential uses in a number of fields including combating the COVID-19 pandemic for instance.

    LDL cholesterol is an important contributor to the risk of coronary heart disease, and its measurement is central to evaluating the effects of lipid-modifying therapies. Several ‘LDL-cholesterol’ assays exist but their methodologies differ, leading to between-assay heterogeneity in values of ‘LDL cholesterol’. We advocate the need for awareness of the potential implications.

    Physiologically relevant ligands for mammalian odorant receptors have been elusive. A mouse odorant receptor–based bioassay has now been used to guide purification and identification of a natural ligand that mediates attraction of female mice to male urine.
