Photo-tuning of highly selective wetting in inverse opals.
Crack-free inverse opals exhibit a sharply defined threshold wettability for infiltration that has enabled their use as colourimetric indicators for liquid identification. Here we demonstrate direct and continuous photo-tuning of this wetting threshold in inverse opals whose surfaces are functionalized with a polymer doped with azobenzene chromophores.
متن کاملCombinatorial wetting in colour: an optofluidic nose.
We present a colourimetric litmus test for simple differentiation of organic liquids based on wetting, which achieves chemical specificity without a significant sacrifice in portability or ease-of-use. Chemical specificity is derived from the combination of colourimetric wetting patterns produced by liquids in an array of inverse opal films, each having a graded wettability, but using different...
متن کاملA Fast Colourimetric Assay for Lead Detection Using Label-Free Gold Nanoparticles (AuNPs)
A sensitive colourimetric method for lead (PbII) detection is reported in this paper using a common tripeptide, glutathione (GSH), and label-free gold nanoparticles (AuNPs). A limit of detection of 6.0 ppb in water was achieved and the dynamic linear range was up to 500 ppb. Selectivity over fourteen potential interfering metal ions was tested and most of these metal ions do not interfere with ...
متن کاملMultipath colourimetric assay for copper(II) ions utilizing MarR functionalized gold nanoparticles
We use the multiple antibiotic resistance regulator (MarR), as a highly selective biorecognition elements in a multipath colourimetric sensing strategy for the fast detection of Cu2+ in water samples. The colourimetric assay is based on the aggregation of MarR-coated gold nanoparticles in the presence of Cu2+ ions, which induces a red-to-purple colour change of the solution. The colour variatio...
متن کاملAgreement analysis and spatial sensitivity of multispectral and hyperspectral sensors in detecting vegetation stress at management scales
Remotely sensed imagery is commonly used to map and monitor large land areas based on the ability to detect vegetation stress. Many sensors are available, including both hyperand multispectral, but have varying costs, convenience, and characteristics. There were two objectives in this study: (1) to compare a hyperspectral sensor to two multispectral sensors with regards to each sensor’s ability...
