Dew inspired breathing-based detection of genetic point mutation visualized by naked eye
A novel label-free method based on breathing-induced vapor condensation was developed for detection of genetic point mutation. The dew-inspired detection was realized by integration of target-induced DNA ligation with rolling circle amplification (RCA). The vapor condensation induced by breathing transduced the RCA-amplified variances in DNA contents into visible contrast. The image could be re...
متن کاملNaphthalene-based Azo-azomethine Chemosensor: Naked Eye Detection of Fluoride in Semi-aqueous Media
A new azo-azomethine chemosensor containing active phenolic sites, H2L, has been designed and synthesized for rapid detection of inorganic fluoride over the other anions, such as Clˉ, Brˉ, Iˉ, AcOˉ, H2PO4ˉ, NO3ˉ, N3ˉ in DMSO/water (90/10) media. The 1H NMR titration revealed that the colorimetric response was considered to be the direct consequence of hydrogen-bond formation between phenolic gr...
متن کاملNaked eye detection of lung cancer associated miRNA by paper based biosensing platform.
This letter demonstrates a biosensing platform for naked eye detection of miRNA, fabricated using a poly(vinylidene fluoride) thin paper impregnated with positively charged poly(3-alkoxy-4-methylthiophene) as luminescent reporters. The miRNA assay is based on the formation of a duplex and a triplex species between the "reporter and miRNA" and "reporter and miRNA-peptide nucleic acid (PNA) hybri...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
A micro dew point sensor with a thermal detection principle
We present a dew point temperature sensor with the thermal detection of condensed water on a thin membrane, fabricated by silicon micromachining. The membrane (600 × 600 ×∼1 μm3) is part of a silicon chip and contains a heating element as well as a thermopile for temperature measurement. By dynamically heating the membrane and simultaneously analyzing the transient increase of its temperature i...
