Aptamer Functionalized DNA Hydrogel for Wise-Stage Controlled Protein Release
With the simple functionalization method and good biocompatibility, an aptamer-integrated
DNA hydrogel is used as the protein delivery system with an adjustable release rate and time by using complementary sequences (CSs) as the biomolecular trigger. The aptamer-functionalized DNA hydrogel was prepared via a one-pot self-assembly process from two kinds of DNA building blocks (X-shaped and L-s...

Highly sensitive self-complementary DNA nanoswitches triggered by polyelectrolytes
Dimerization of two homologous strands of genomic DNA/RNA is an essential feature of retroviral replication. Herein we show that a cationic comb-type copolymer (CCC), poly(L-lysine)-graft-dextran, accelerates the dimerization of self-complementary stem–loop DNA, frequently found in functional DNA/RNA molecules, such as aptamers. Furthermore, an anionic polymer poly(sodium vinylsulfonate) (PVS) ...

Photo-induced DNA Cleavage in Self-assembly Multilayer Films
Electrostatic self-assembly multilayer films have been successfully fabricated from a C-60-ethylenediamine adduct (C-60-EDA), and DNA. Under visible light irradiation, the DNA is cleaved and the films are destroyed. The photo-induced reaction follows a direct electron-transfer mechanism. A high oxygen concentration in the solution enhances the reaction, while separation of C-60-EDA and DNA retards...

Induced Circular Dichroism of Anionic Porphyrin TPPS Aggregates in DNA Solutions
Induced circular dichroism (CD) of achiral anionic tetrakis (4-sulfonatophenyl) porphine (TPPS) in polyanionic DNA solutions was investigated. Induced CD signals of the anionic TPPS aggregates in both cholesteric liquid crystal DNA solutions and isotropic DNA solutions are all observed within an appropriate pH range. When the pH value is less than 5, the induced CD signals of TPPS are split i...

The preparation of nano-scope chitosan-oligomer copper complexes and their interaction with DNA
Water-soluble low molecular weight chitosan of nanometer level and its copper complexes were prepared, and characterized by IR spectra, elemental analysis and gel permeation chromatography (GPC). The modes and mechanism of these copper complexes interaction with DNA were studied by a fluorescent probe method and electrophoresis analysis. It is suggested that there are electrostatic and intercalati...

STUDIES ON THE INTERACTION OF DNA AND WATER-SOLUBLE POLYMER-SUPPORTEDSCHIFF BASE COMPLEX
The modes and activities of the interaction of DNA and water-soluble polymer
supported Schiff base nickel complex, which has been prepared by copolymerization,
have been discussed according to the fluorescent probe method. It
indicates that the polymer matrix effect and increasing solubility in water can
increase the interaction of this polymer metal complex with DNA.tr

Characterization of DNA-loaded porous polyethersulfone particles prepared by phase inversion technique
In this study, DNA-loaded polyethersulfone (PES) porous particles were prepared by means of a liquid-liquid phase separation technique. The porous structure parameters and the diameter of the particles were then determined. It was found that the PES concentration strongly affects the porous structure and the specific surface area of the particles. By manipulating the preparation conditions, ...

DNA 在受限管道中的回复
关键字：：DNA 管道受限，回复，热力学
我们采用粗粒化 DNA 分子模型和副本交换分子动力学方法，研究了受限在管道中的两条单链 DNA 的回复行为，考察了受限对 DNA 回复热力学性质的影响。通过统计不同温度下的 DNA 碱基的配对数获得融解曲线，发现融解温度随着受限尺寸的减小而增大。热容曲线反映相似的规律：随着受限尺寸的减小，热容峰向高温方向移动，峰高逐渐降低，同时峰变宽。我们考察了四种不同的序列在不同受限条件下的...
