Surface plasmon resonance-based biosensors: From the development of different SPR structures to novel surface functionalization strategies

Surface plasmon resonance (SPR)-based biosensors are very powerful tools for the study of biomolecular interactions, chemical detection and immunoassays. This paper reviews the performance of various SPR structures and detection schemes focusing on propagating surface plasmons generated in planar structures. Some aspects of their surface functionalization, the key element which imparts biofunctionality to these structures and hence transforming them into biosensors, will also be discussed accordingly. The ultimate performance of SPR-based biosensors will thus be determined by both their inherent optical performance and suitable surface functionalization.     

Experimental and numerical study of gas dynamics of exhaust pipe of gas turbine unit

A few geometrical configurations of exhaust pipe of marine gas turbine unit were investigated experimentally in NPP"Mashproeykt" (Nikolaeyv, Ukraine) and numerically with objective of solver verification and to determine the optimal configuration with minimal level of total pressure loss.
