A polypyrrole nanotube containing nanoparticles is prepared by a dual template approach, and the inside of the nanotube is selectively functionalized with carboxyl and amine groups.
Mg(2+) can lead to the fluorescence enhancement of a dye molecule as high as 47.3-fold while L-proline acts as a promoter in this multicomponent sensory system. The fluorescence color could be easily detected by the nake...
We report the formation of highly-ordered self-assembled monolayers of an achiral organic semiconductor molecule. STM results show spontaneous formation of very large single domains of ordered chiral monolayers. DFT calc...
We developed catalytic intermolecular C(sp(3))-C(sp(3)) cross-couplings between various allyl alcohols and allyl boronates, which proceeded smoothly in the presence of nickel(0) under mild conditions to form 1,5-dienes w...
A novel glucose-responsive controlled release of insulin system is constructed through coating enzyme multilayers on mesoporous silica particles (MSPs). The MSPs serve as the drug reservoir, and the enzyme multilayers cr...
A concise method for the formation of cyclopyrophosphate of cIDPRE as well as sulfur and selenium-substituted pyrophosphate cIDPRE analogues ( P(S)(1)-cIDPRE, P(Se)(1)-cIDPRE, P(S)(2)-cIDPRE and P(Se)(2)-cIDPRE) was repo...
It was first demonstrated that the DNA probe modified with ribonucleotides can be efficiently ligated by using miRNA as the template. With PCR amplification of the ligated DNA probe, as low as 0.2 fM target miRNAs can be...
BzSe-Cy is a small-molecule fluorescent probe containing Se, which can respond reversibly to changes in ONOO(-) or reduced ascorbate and exhibit high sensitivity and selectivity for ONOO(-).
Two newly synthesized naphthodithiophene-based copolymers, PNB, exhibit a low optical bandgap of similar to 1.64 eV with which the solar cells fabricated from the blend of PNB and PC(71)BM afforded a power conversion eff...
A new copolymer of dithienosilole and dithienylthiazolo[5,4-d]thiazole with a hexyl side chain on the 4-position of thiophene units was designed and synthesized. Polymer solar cells based on the polymer as a donor and PC...
A novel electrochemical method to detect hepatitis C virus was developed based on site-specific cleavage of BamHI endonuclease and enzymatic signal amplification with horseradish peroxidase-encapsulated nanogold hollow s...
A random donor-acceptor semiconducting copolymer based on diketopyrrolopyrrole as the acceptor unit and dithienothiophene as the donor unit has been synthesized and characterized. Preliminary studies of BHJ solar cells b...
Atomic force microscopy reveals that Pseudomonas aeruginosa LecA (PA-IL) and a tetra-galactosylated 1,3-alternate calix[4]arene-based glycocluster self-assemble according to an aggregative chelate binding mode to create ...
The excited state crystal structure of the ionic complex (Nd(DMA)(4)(H(2)O)(4)-Fe(CN)(6)center dot 3H(2)O (DMA = dimethylacetamide) has been determined at 15 K upon UV illumination by single crystal X-ray diffraction. Si...
Two deuteriumed quasi-one-dimensional (quasi-1D) spin-Peierls-type compounds, 4-X-benzylpyridinium-d(5) bis(maleo-nitriledithiolato) nickelate (the substituent X = Br or Cl), were structurally characterized. Compared wit...
A new water-soluble anionic conjugated polyelectrolyte with a nitroxide radical covalently linked to the sulfonated poly(phenylene ethynylene) backbone (PPE-SO(3)) is reported. This radical-functionalized PPE-SO(3) (RF-P...
