Occasionally referred to as ‘colloidal gold,’ gold colloid is a suspension comprising sub-micron gold nanoparticles suspended in a solvent - most commonly water. Gold nanoparticles' distinct ...

THE second edition of this work, like the first, is well adapted to introduce the general student to the subject, the theoretical portions and the accounts of experimental procedure being well ...

Colloidal nanocrystals (CNs) are artificially grown inorganic particles stabilized by surfactants. Those smaller than 10 nm can transform their optical and electronic properties and exhibit a quantum ...

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. Scientists have devised a way of ...

Lateral flow immunoassays, also called immunochromatography strips, are straightforward devices used to detect the absence or presence of a target analyte. Target analytes range from pathogens to ...
