A colorimetric estimation of lipopolysaccharides
FEBS Letters, 1971 The lipopolysaccharides of Gram-negative bacteria are not confined to cell walls but may accumulate in culture fluids of cells grown under certain conditions [l-3] . Study of this accumulation has been aided by development of a calorimetric estimation for lipopolysaccharides which is specific, sensitive and technically simple in comparison with methods

Advanced Materials Technologies, EarlyView.A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.
