Silicon nanopillars as a platform for enhanced fluorescence analysis.

The importance of fluorescent detection in many fields is well established. While advancements in instrumentation and the development of brighter fluorophore have increased sensitivity and lowered the detection limits of the method, additional gains can be made by manipulating the local electromagnetic field. Herein we take advantage of silicon nanopillars that exhibit optical resonances and field enhancement on their surfaces and demonstrate their potential in improving performance of biomolecular fluorescent assays.

[The monitoring of application of dabigatran as a remedy of prevention of thromboembolic complications after hip joint arthroplasty].

The analysis was applied to the indicators of hemostasis system under application of new anticoagulant, dabigatran etexilat, after hip joint arthroplasty. It is established that among the coagulation methods analysis the most specific to the effect of dabigatran is the testing of thrombin and echitox time of coagulation. Considering low sensitivity of the echitox to anticoagulation effect of D-dimer the echitox test is optimal for laboratory monitoring of application of dabigatran after orthopedic intervention.

[Pathophysiological features of dorsalgia development among railway workers, connected with railway communication].

Dorsalgia's is an actual medical and social problem. It gains prominent significance among railway workers, connected with railway communication. Pain syndromes among this group of patients have different complex pathogenetic mechanisms of the development.

Silicon nanopillars for field-enhanced surface spectroscopy.

Silicon nanowire and nanopillar structures have drawn increased attention in recent years due in part to their unique optical properties. Herein, electron beam lithography combined with reactive-ion etching is used to reproducibly create individual silicon nanopillars of various sizes, shapes, and heights. Finite difference time domain analysis predicts local field intensity enhancements in the vicinity of appropriately sized and coaxially illuminated silicon nanopillars of approximately 2 orders of magnitude.
