Numerical Modeling of a Metamaterial Biosensor for Cancer Tissues Detection
In this paper, the numerical design and simulate a biosensor to detect tumors and cancerous tissues by using metamaterial structures in the microwave regime are presented. The presented structure consists of a microstrip transmission line and a split ring resonator (SRR) that form a bandpass filter and has a unique resonance frequency. Given that cancerous tissues have larger volumes of water t...
متن کاملEfficient and Rapid Detection of Salmonella Using Microfluidic Impedance Based Sensing
We present a low cost, easy to fabricate biosensor, which can quickly and accurately detect Salmonella typhimurium. This study also compares the advantages of the microfluidic biosensor over a nonmicrofluidic biosensor. High density interdigitated electrode array was used to detect Salmonella cells inside a microfluidic chip. Monoclonal anti-Salmonella antibodies were allowed to be immobilized ...
متن کاملReal-time biomolecular binding detection using a sensitive photonic crystal biosensor.
Real-time measurement of specific biomolecular interactions is critical to many areas of biological research. A number of label-free techniques for directly monitoring biomolecular binding have been developed, but it is still challenging to measure the binding kinetics of very small molecules, to detect low concentrations of analyte molecules, or to detect low affinity interactions. In this stu...
متن کاملMonitoring and Control of Grain Storage Using Plc
Grain storage occupies a vital role in the economies of developed and developing countries. Proper monitoring of grain storage is essential to reduce grain loss. The present system involves human effort in most of the activities which reduces work efficiency and increases time consumption. These difficulties can be avoided by our proposed project. In this project, the controlling and monitoring...
متن کاملمقایسه اثر کاربرد لجن فاضلاب و کود شیمیایی بر عملکرد و غلظت برخی عناصر غذایی در گیاه اسفناج (Spinosa olerace L.) در سه بافت یک خاک آهکی
Abstract Addition of sewage sludge (SS) in soil causes increasing soil organic matter, which in turn improves soil physical properties, and could supply part of the nutrients required by plants. For comparison of SS application and chemical fertilizer treatment (CFT) on yield and concentration of some macro and micro nutrients in spinach, a greenhouse factorial experiment, arranged in a comple...
