Development of an aptasensor for electrochemical detection of exosomes.
Exosomes are small (50-100 nm in diameter) vesicles secreted from various mammalian cells. Exosomes have been correlated with tumor antigens and anti-tumor immune responses and may represent cancer biomarkers. Herein, we report on the development of an aptamer-based electrochemical biosensor for quantitative detection of exosomes. Aptamers specific to exosome transmembrane protein CD63 were imm...
متن کاملDetection of lead ions using an electrochemical aptasensor
The aim of this research was to develop a simple, selective and sensitive aptasensor for detection of Pb2+ based on hairpin structure of complementary strand (CS) of aptamer (Apt). Screen printed carbon electrode (SPCE) was electrodeposited by gold nanoparticles to be used as the substrate for the immobilization of Apt-CS. Moreover, gold nanoparticles (AuNPs) and thionine were added to increase...
متن کاملDevelopment of an aptasensor for electrochemical detection of tetracycline
Developing the rapid, simple and sensitive biosensor system for tetracycline detection is very important in food safety. In this paper, we developed a label-free aptasensor for electrochemical detection of tetracycline. The reorganization of tetracycline binding aptamer was confirmed by Isothermal Titration Calorimetry, Kd 1⁄4 5.18 10 5 mol L 1. According to the electrochemical impendence spect...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولElectrochemical aptasensor for tetracycline detection.
An electrochemical aptasensor was developed for the detection of tetracycline using ssDNA aptamer that selectively binds to tetracycline as recognition element. The aptamer was highly selective for tetracycline which distinguishes minor structural changes on other tetracycline derivatives. The biotinylated ssDNA aptamer was immobilized on a streptavidin-modified screen-printed gold electrode, a...
