چکیده

Duplex-based, fluorescent sensors bearing cyclodextrins as a guest-binding moiety were synthesised based on Click chemistry, and the sensors selectively detected unsaturated fatty acids by pyrene-emission switching from monomer to excimer.

[DNA duplex-based fluorescence probes/sensors using monomer-excimer switching].

In this review, we report DNA duplex-based fluorescence probes/sensors using pyrene monomer-excimer switching. The review mainly comprises two topics: 1) excimer-monomer switching molecular beacons (EMS-MB) and 2) monomer-excimer switching sensors based on the structural motif of antibodies. The EMS-MBs have two pyrene fluorophores connected both at 3' and 5' ends of a single-stranded oligonucl...

A chromatographic method for detection of palm oil in butter

Replacement with the cheaper animal fats or vegetable oils is conventional in milk through direct incorporation or homogenization of skimmed milk with less expensive foreign fats. The main objective of the present study was to evaluate the capability of a simple, fast, and reliable method for the detection of added palm oil in butter. The butter samples were mixed with palm oil (0.5-50 wt%) fol...

Determination and study the fatty acid contents and their seasonal variations by temperature of a dominant bivalve(Callista umbonella) of Haleh Creek

In this study fatty acid contents, because of the importance in human’s life, and their seasonal variations of a dominant bivalve of Haleh Creek were determined for the first time. Fatty acid identification was done by GC-MS (Gas Chromatography–Mass Spectrometry) method. After collecting and dissecting the species from the shells, samples weighed and frozen for further experiments. All the samp...

Calix[4]arene triazole-linked pyrene: click synthesis, assembly on graphene oxide, and highly sensitive carbaryl sensing in serum.

A fluorescent calix[4]arene triazole-linked pyrene (CP) was carefully designed and synthesized via click chemistry. The modification of CP with graphene oxide (GO) by a simple non-covalent interaction strategy is presented. Further inspection by electrochemical impedance spectroscopy reveals that the CP-GO could exhibit a very high supramolecular recognition for carbaryl, in particular in serum...
