Manipulation of magnetic nanoparticles by optically induced dielectrophoresis

2022 IEEE International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO) (2017)

Ying Wang Feifei Wang Tingting Huang Fenfen Guo Ying Xie

This paper presents a method for the manipulation of magnetic nanoparticles by optically induced dielectrophoresis (ODEP) device that can realize the transportation and convergence of nanoparticles. ODEP can be realized with a sandwich structure of three layers including the photoconductive layer, the liquid layer with the sample and the indium tin oxide electrode (ITO) layer. In this work, magnetic nanoparticles with the diameter of 10-100nm were successfully manipulated by positive dielectrophoresis force. The solution with magnetic nanoparticles on a mica substrate placed in the sandwich structure was dried in the air and imaged by atomic force microscope (AFM). The AFM images showed that the magnetic nanoparticles were converged in the illumination area. This method can be used to manipulate magnetic nanoparticles.

DNA network structures induced by ferric ions on mica surfaces

2022 IEEE International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO) (2016)

Lu Zhao Zuobin Wang Wenxiao Zhang Ying Wang Xinyue Wang

This paper explores the changes of DNA network structures with different solution concentrations of DNAs and ferric ions by atomic force microscope (AFM). AFM is a powerful tool for both the observation and manipulation of biological molecules. DNA is an important life molecule to record the biological information and it is also a natural nano material which has great potential for the fabrication of molecular devices. The mica with a flat surface can be used as a substrate for observing DNA molecules, but the combination with DNA is not controllable, and the mica surface has to be modified. Here, we used ferric ions to induce DNA network structures and they were investigated by AFM. It was observed that when the concentration of DNA solution was low, there was no DNA network structures formed, and when the concentration of DNA solution was increased to 200-280ng/ul, DNA network structures were clearly formed.

Stretching of DNA molecules on mica surfaces by magnetic field

2022 IEEE International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO) (2017)

Feifei Wang Ying Wang Tingting Huang Fenfen Guo Jinyun Liu

This paper presents a method for the stretching of DNA molecules on mica surfaces by magnetic field. In the experiment, the magnetic fields with different intensities were generated using a cylindrical coil and were used to study their effects on DNA molecules. The magnetic field intensity was controlled by the electric current flowing through the coil. The imaging of DNA molecules was performed by atomic force microscope (AFM) in the same position on the mica surface after the treatment with the magnetic field. It was found that the DNA molecules were gradually straightened with the increase of magnetic field intensity, and the straightening performance was better than that of the molecular combing method in the experiment. In addition, the degree of DNA straightening was related to the speed at which DNA molecules were dropped to the mica surface, the amount of DNA charges and the direction of magnetic field.

Synthesis, Structure, and Photoluminescence Property of a New Cd(II) Complex Based on 4-(2′,3′-Dicarboxylphenoxy) Benzoic Acid

Synthesis and Reactivity in Inorganic Metal-Organic and Nano-Metal Chemistry (2014)

Xiaodong Li Yanli Xie Fenfen Guo Meng-Di Tu Hongli Du

A new complex, namely [Cd(HL)(H2O)2]n (H3L = 4-(2′,3′-dicarboxylphenoxy) benzoic acid), has been hydrothermally synthesized by the reaction of H3L ligand and CdI2, and characterized by elemental analysis and IR spectroscopy. Single-crystal X-ray analysis shows that complex 1 belongs to the monoclinic system, P2(1)/n space group, a = 6.0658(7) Å, b = 8.7787(11) Å, c = 29.510(4) Å, β = 92.2920(10)º, F (000) = 888, R1 = 0.0197, wR2 = 0.0514. The Cd centers are bridged by L3− ligands to form a 2D network that is further extended into a 3D framework by several sorts of hydrogen bonding interactions. Moreover, the thermal and luminescence properties of 1 have also been investigated.

Imaging of DNA molecules by atomic force microscope

2022 IEEE International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO) (2017)

Fenfen Guo Feifei Wang Ying Wang Wenxiao Zhang Xinyue Wang

This paper explores suitable conditions for the imaging of DNA molecules by atomic force microscope (AFM). As a typical biological macro-molecule, DNA with genetic information has attracted extensive attention, which is an important research subject in molecular biology and biomedicine. In this work, 3-Aminopropyl Triethyl Silane (APTES), Ni ² + and Mg ² + were used to modify the surface of mica substrate, and DNA molecules were adhered to the mica surface through the physical interaction of charges. The DNA molecules were imaged using an AFM under both air and liquid conditions. By analyzing the images of DNA molecules obtained in the experiments, it was found that the mica surface modified with Ni ²⁺ had the best imaging quality under the liquid condition. This work will be useful for the study of high quality AFM imaging of DNA molecules, and the manipulation of DNA molecules by AFM mechanical forces.
