bioelectronics has attracted increasing interest in recent years because of their applications in various disciplines, such as biomedical. development of efficient bio-nano hybrid materials is a new move towards revolution of nano-bioelectronics. a novel nano-bio hybrid electrode based on zno–protein for bioelectronics applications was prepared and characterized. the electrode was made by coval...
Scanning Probe Microscopy has been routinely employed as a surface characterization technique for nearly 20 years. Atomic Force Microscopy is the most widely used subset of SPM, which can be used in ambient conditions with minimum sample preparation. AFM is able to measure three-dimensional topography information from the angstrom level to the micron scale with unprecedented resolution. This pa...
Aflatoxin M(1) (AFM(1)) is a hydroxylated metabolite of aflatoxin B(1) (AFB(1)). After it is formed, it is secreted in the milk of mammals. Despite the potential risk of human exposure to AFM(1), data reported in literature on the metabolism, toxicity, and bioavailability of this molecule are limited and out of date. The aim of the present research was to study the absorption profile of AFM(1) ...
through PeakForce QNMTM, 3) correlated nanoscale AFM-based conductivity measurements are a powerful technique for nanometer-scale electrical characterization on a wide range of samples. Traditionally, these measurements have been categorized into two classes: Conductive AFM (CAFM), which covers the higher current range (sub-nA up to μA), and Tunneling AFM (TUNA), which covers the lower current ...
در این تحقیق لایه های نازک مس بر زیرلایه ی نیم رسانای گالیوم آرسناید نوع n به دو روش الکتروانباشت و الکترولس رشد داده شدند. لایه های الکتروانباشت شده با مد جریان ثابت از ma 5 تاma30 و لایه های الکترولس شده در دماهای مختلف oc 25، oc77 تهیه شدند. ساختار و ریخت شناسی لایه ها به کمک دستگاه های xrd و sem مورد بررسی قرار گرفت. سپس پارامتر زبری لایه های الکتروانباشت شده در جریان های مختلف انباشت و هم ...
v-shaped and triangular cantilevers are widely employed in atomic force microscope (afm) imaging techniques due to their stability. for the design of vibration control systems of afm cantilevers which utilize patched piezo actuators, obtaining an accurate system model is indispensable prior to acquiring the information related to natural modes. a general differential quadrature element method (...
INTRODUCTION Extracellular vesicles (EVs) are shed from cells and carry markers of the parent cells. Vesicles derived from cancer cells reach the bloodstream and locally influence important physiological processes. It has been previously shown that procoagulant vesicles are circulating in patients' fluids. These EVs are therefore considered as promising biomarkers for the thrombotic risk. Becau...
Dynamic atomic force microscopy, in essence, consists of a vibrating microcantilever with a nanoscale tip that interacts with a sample surface via shortand long-range intermolecular forces. Microcantilevers possess several distinct eigenmodes and the tip-sample interaction forces are highly nonlinear. As a consequence, cantilevers vibrate in interesting, often unanticipated ways; some are detri...
Membrane vesicles (AFM ) were isolated from cell-free ascites fluid of Moloney virus-induced lymphoma-bearing mice. Biochemical analysis has indicated that the AFM. fraction is highly enriched in the plasma membrane en zyme marker 5 -nucleotidase. Neither reduced nicotinamide adenine dinucleotide dehydrogenase nor succinic dehydrogenase could be detected in the AFM,, fractions, indicating their...
