Recently sensors based on the group III nitrides attract growing interest in the scientific comunity. It has been shown that sensors made of this material are suitable for recording action potential of muscle cells or [...]
Pt, Ir, Au and few other precious metals have highly conducive electrical and chemical properties; hence have been widely used in pH sensors and biomolecular sensing applications. The chief objective of this research is to [...]
Abstract Cell adhesion is an active process, carried out in vivo via receptor ligand-like interactions between cell surface adhesion molecules and the extracellular matrix. Initial cell surface reactions following contact may trigger multiple responses, which [...]
This work presents a low power microstrip transmission line PCR thermo-cycler based on microwave heating that is designed for low-budget, portable/Point of Care (POC) genetic analysis. Previous efforts on miniaturized PCR chambers focused mainly on [...]
Matrix Assisted Laser Desorption Ionization Mass Spectroscopy (MALDI MS) is a particularly efficient tool for proteomics research and diagnostics with protein biomarkers. Recent innovations in the application of inorganic matrices have enabled a reduction in [...]
Many current bioanalytical and diagnostic methods rely on labeling the species of interest and specialized detection equipment to monitor the label. Common techniques suffer from signal loss or degradation and require the use of equipment [...]
Previously, we demonstrated a system that can detect the presence of yeast cells using capacitance measurements from a cavity resonator. The resonator is coupled to a set of electrodes, which are aligned 90 degrees relative [...]
Inexpensive and rapid methods for detecting bacterial infections and their corresponding susceptibility to antibiotics are desperately needed. The determination of which antibiotic to use and its administration at dosages that will effectively suppress bacterial growth [...]
We present here the development of a polymer nanocomposite based gas sensor for detecting trace gas emissions in ambient environment. This project is aimed to build a chemiresistive gas sensor with excellent sensitivity and improved [...]
AAO(Anodic Aluminum Oxide) film is fabricated as a sensing material of capacitive humidity sensors. Because AAO films have a lot of nano-size pores, many water vapors can be absorbed. The size of a pore diameter [...]
One of the most fascinating fields of nanodevice research is its application to the detection of biologically important entities such as DNAs, peptides, antigens, enzymes, viruses, and cells. Nanoelectronic devices adopted in this study are [...]
5x5 arrays of six nano-transistor devices were fabricated on p-type silicon/silicon oxide (200nm) wafers with resistivity 1-100 -cm. 50nm of doped polysilicon were deposited and annealed to make nanowires. All nanowires were made with direct [...]
The concentration of Escherichia coli (E.coli) cells in water was detected by depositing them on an array of electrodes using dielectrophoresis (DEP). Electrowetting was used to effectively concentrate the E.coli in a droplet of water [...]
In this paper we introduce a wearable device combining physiological monitoring and person’s position assessment. An accelerometer is used as a multi-functional sensor for a position and heart mechanical performance measurements, known as mechanocardiography (MCG). [...]
We demonstrate a standoff passive sensor working in the near infrared range. The device uses a platform based on dielectric and metallo-dielectric layers. The sensor demonstrated a significant change in the reflection coefficient if exposed [...]
This paper describes a robust minutiae-based fingerprint identification method suitable for use in small populations. System employs two serially connected neural networks in which fingerprint feature extraction is carried out by the first network – [...]
SPR ( surface Plasmon Resonance) is an non destructive sensor capable of measuring the changes in refractive index above the gold surface (~300 nm) .The advantage of the SPR is in its capability of looking [...]
We demonstrate an innovative method of PCR product identification that is based on thermal denaturation of PCR products which are immobilized on microbeads using integrated BioFET. Purification step was finished simply by capturing the biotinylated [...]
A photonic band-gap nanosensor based on porous silica is proposed in the study. The photonic band-gap silica nanosensor is easy to fabricate and simple to use. Its optical characteristics can be easily modulated by electrochemical [...]
Traditionally, growth based techniques have been the standard in environmental monitoring for evaluating the quality and quantity of microbial content. However, many studies have underscored the inadequacy of these techniques: (1) to provide environmental microbial [...]
A magnetoelastic (ME) platform coated with a bio-molecular recognition element (bacteriophage) for selective and specific recognition of Bacillus anthracis spores is described. ME materials have a mass-sensitive, characteristic, resonant frequency. In response to the binding [...]
