Image Area

In a series of recently published works, we demonstrated that the plasmon-assisted microscopy of nano-objects (PAMONO) technique can be successfully employed for the sizing and quantification of single viruses, virus-like particles, microvesicles and charged non-biological particles. This approach enables label-free, but specific detection of biological nano-vesicles. Hence, the sensor, which was built up utilizing plasmon-assisted microscopy, possesses relative versatility and it can be used as a platform for cell-based assays. However, one of the challenging tasks for such a sensor was the ability to reach a homogeneous illumination of the whole surface of the gold sensor slide. Moreover, in order to enable the detection of even relatively low concentrations of nano-particles, the focused image area had to be expanded. Both tasks were solved via modifications of previously described PAMONO-sensor set ups. Taken together, our latest findings can help to develop a research and diagnostic platform based on the principles of the surface plasmon resonance (SPR)-assisted microscopy of nano-objects.

Bioanalytical Application

An novel optical nano biosensor based on gold capped nano-particles for detecting binding events between ligands and receptor molecules as well as interactions among proteins without use of labels has been presented in this paper. The optical properties of nano-sized gold particles exhibiting pronounced adsorption in the visible region which called as localized surface plasmon resonance (LSPR) have been exploited, whose peak wavelengths depended exquisitely on the refractive index of the surrounding. In comparison with surface plasmon resonance (SPR) technology, the optical nano biosensor possessed high sensitivity, surprisingly low “bulk effect”, ease of preparation, and low-cost polymer based fabrication, which opened a promising bioanalytical application in practice.

In order to determine the minimum thickness of cutting under different cutting condition of aluminum alloy materials 2A12 of micro-milling, research the size effect caused by the cutting edge radius and few microns per tooth in micro-milling process. Using thermal coupling model of Johnson-Cook as a material model of the workpiece, using Johnson-Cook shear failure of the law as part of the failure criteria, using coupled plane strain thermal units and hybrid adaptive grid technology to mesh, the friction between the tool and workpiece take the amendment Coulomb's law that combine with the sliding friction areas and areas of the adhesive friction, to the micro-milling by nonlinear and elastic-plastic finite element simulation. Through finite element analysis, the ratio of minimum radius of thickness to the cutting edge tool radius under different conditions of cutting speed and cutter blade was got, the size effect, stress field and cutting force under different cutting depth was got, and comparing and analysis the results, getting the various factors impact on the size effect of micro-milling, it provide a basis for the actual processing.
