Since the discovery of the two-dimensional (2D) carbon material, graphene, just over a decade ago, the development of graphene-based field effect transistors (G-FETs) has become a widely researched area, particularly for use in point-of-care biomedical applications. G-FETs are particularly attractive as next generation bioelectronics due to their mass-scalability and low cost of the technology'...

Interest in biosensors based on field-effect transistors (FETs), where an electrically operated gate controls the flow of charge through a semiconducting channel, is driven by the prospect of integrating biodetection capabilities into existing semiconductor technology. In a number of proposed FET biosensors, surface interactions with biomolecules in solution affect the operation of the gate or ...

BACKGROUND Spirometry as a non-invasive and inexpensive test is widely used for occupational health evaluations. Bronchodilator test is used for the assessment of airflow limitation and increase in forced expiratory volume in 1 second (FEV1) or forced vital capacity (FVC) is considered as a positive response. This study was performed to assess the response of forced expiratory volume in 6 secon...

BACKGROUND The extremes of BMI are associated with an increased risk of miscarriage both in spontaneously conceived pregnancies and after fertility treatment. The aim of the present study was to study the effect of BMI on miscarriage rate (MR) in fresh IVF/ICSI, and in spontaneous and hormonally substituted frozen-thawed embryo (FET) cycles. METHODS Analysis was carried out on 3330 first preg...

New oligomers containing a pyrazine unit have been prepared: the bithienyl derivatives afforded p-type FET devices whereas the trifluoromethylphenyl derivatives showed n-type FET behavior.

The authors develop a theory of photodetection in double-gated bilayer graphene (BLG) field-effect transistor (FET), following the Dyakonov-Shur scheme based on nonlinear mixing plasma waves. A BLG channel displays peculiar effect: band gap depends intensity wave, which makes photoresponse dependent FET electrostatics. work here bridges microscopic features electronic dispersion two-dimensional...

In this paper, a novel algorithm for transient linear circuit analysis based on the Finite Element Technique (FET) was established. The FET procedure allows straightforward solution complex electric circuits since it is Method (FEM) approach. developed us to select various types of time integration schemes when forming local system equations coupled finite element. To illustrate basic principle...

The formation of microvascular networks plays essential roles in regenerative medicine and tissue engineering. Nevertheless, the self-organization mechanisms underlying the dynamic morphogenic process are poorly understood due to a paucity of effective tools for mapping the spatiotemporal dynamics of single cell behaviors. By establishing a single cell nanobiosensor along with live cell imaging...

OBJECTIVE To compare the ablation characteristics of the moving-shot technique (MST) and the fixed electrode technique (FET) for radiofrequency (RF) ablation in an ex-vivo bovine liver tissue model. MATERIALS AND METHODS We performed RF ablation using FET in 110 bovine liver blocks using 11 different ablation times ranging from 5 seconds to 5 minutes (10 blocks per each time duration). Ten bo...
