Rapid engineering of versatile molecular logic gates using heterologous genetic transcriptional modules

09-10-2014 | Baojun Wang; Martin Buck, Chemical Communication, 2014

We designed and constructed versatile modular genetic logic gates in bacterial cells. These function as digital logic 1-input Buffer gate, 2-input and 3-input AND gates with one inverted input and integrate multiple chemical input signals in customised logic manners. Such rapidly engineered ...

Stimuli-responsive cancer therapy based on nanoparticles

09-10-2014 | Jing Yu; Xin Chu; Yanglong Hou, Chemical Communication, 2014

Nanoparticles (NPs) have recently been well investigated for cancer therapy. Among them, those that are responsive to internal or external stimuli are promising due to their flexibility. In this feature article, we provide an overview on stimuli-sensitive cancer therapy, using pH- and ...

Discrimination of Chemical Profiles of Some Bacterial Species by Analyzing Culture Headspace Air Samples Using TD-GC/MS

09-10-2014 | Ratiu, Ileana-Andreea; Bocos-Bintintan, Victor; Turner, Matthew; Moll, Victor-Hugo; Lawrence Paul Thomas, Charles, Current Analytical Chemistry, 2014

Abstract: In an attempt to discriminate and identify several bacterial species, headspace air samples above a series of bacterial cultures were interrogated using a TD-GC/MS system. Three microorganism strains with relatively low pathogenic character – Escherichia coli, Bacillus subtilis and ...

Incorporation of iron hydrogenase active sites into a highly stable metal–organic framework for photocatalytic hydrogen generation

09-10-2014 | Koroush Sasan; Qipu Lin; ChengYu Mao; Pingyun Feng, Chemical Communication, 2014

A new biomimetic heterogeneous photocatalyst ([FeFe]@ZrPF) has been synthesized through the incorporation of homogeneous complex 1 [(í-SCH2)2NC(O)C5H4N]–[Fe2(CO)6] into the highly robust zirconium-porphyrin based metal–organic framework (ZrPF). The immobilized biomimetic [Fe2S2] catalyst inside ...

Emulsification Based Liquid Microextraction Prior to Flame Atomic Absorption Spectrometry for Sensitive Determination of Copper in Water Samples

09-10-2014 | Mahdi Zahedi, Mir; Rahimi-Nasrabadi, Mehdi; Rai, Hossein; Mahdi Pourmortazavi, Seied; Banan, Alireza, Current Analytical Chemistry, 2014

Abstract: In this study emulsification based liquid microextraction (EBLME) was developed for preconcentration of Cu(II) using a redesigned dispersive liquid - liquid microextraction (DLLME). The procedure is based on an organic extraction solvent and aqueous solution of surfactant system ...

Improvised Response in 1,4 Dioxane as Co-solvent During Selective Determination of Cerium (III) in Binary Mixtures by Conductometry

09-10-2014 | Matharu, Komal; Kumar SK, Ashok; K Mittal, Susheel, Current Analytical Chemistry, 2014

Abstract: The influence of different protic and aprotic solvents on the conductometric titrations of cerium(III) with EDTA has been studied. The results are explained for mixed solvent systems using 1,4-dioxane (DA), acetonitrile (ACN), Dimethylsulphoxide (DMSO), N,N’-dimethylformamide (DMF), ...

Selective Ligandless Cloud Point Extraction of Gold from Wastewater and ore Samples

09-10-2014 | Zia Mohammadi, Sayed; Mohammadnezhad, Mohsen; Afzali, Daryoush; Amiri, Asghar, Current Analytical Chemistry, 2014

Abstract: A selective and sensitive cloud point extraction procedure for the preconcentration of trace amounts of gold prior to their determination by flame atomic absorption spectrometry has been developed. The cloud point extraction method is based on the formation AuI3 and then entrapped ...

Simple, Direct and Simultaneous Stripping Voltammetric Determination of Lead and Copper in Gasoline Using an In Situ Mercury Film Electrode

09-10-2014 | C. Martiniano, Lorena; de M.S. Almeida, Joseany; H.R. Cavalcante, Glene; P. Marques, Edmar; C.O. Fonseca, Teresa; L. ..., Current Analytical Chemistry, 2014

Abstract: An improved procedure is presented to determine Pb(II) and Cu(II) in gasoline using a mercury film electrode generated in situ. The method is based on the reduction of the metal ions at adequate potentials on the glassy carbon electrode, in whose optimized microemulsion medium ...
