  • Impact parameters investigation of DNA immobilisation process on DNA sensor response

    This paper studies impact parameters of DNA sequence immobilisation on DNA sensor response. The parameters were examined including immobilisation time, carbon nanotubes concentration, DNA probe concentration and pH value. The DNA probe sequences were immobilised on surface of microelectrodes by using multi–walled carbon nanotubes (MWCNTs) as mediator. The hybridisation between DNA probe and DNA ...

  • Studies towards a switch–off optical DNA sensor based on poly(p–phenylenevinylene) grafted magnetic beads

    Much effort has been devoted towards developing efficient DNA sensors for applications in medical diagnostics, food contamination, forensics, biodefence and environmental monitoring. In this study we further evaluate the selectivity of our recently developed switch–off sensor design that utilises sandwich hybridisation between a photoluminescent anionic conjugated polymer (CP) bound capture probe ...

  • An electrochemical DNA biosensor for trace amounts of mercury ion quantification

    In this work we report the development of an electrochemical DNA biosensor with high sensitivity for mercury ion detection. A new matrix based on gold nanoparticles (AuNPs)-glutathione (GSH)/cysteine was investigated. The interaction between DNA oligonucleotides and Hg2+ ions followed by the formation of Thymine–Hg2+–Thymine (T–Hg2+–T) structures was quantified using different ...

  • Analytical simulation of interfacial DNA hybridisation for design of an optimal nanotechnology handheld biosensor

    DNA biosensors are becoming ubiquitous at current scale-level of nanotechnology; but still remain in research laboratory. The project objective is accessing feasibility for a commercial off-the-shelf optimally designed versatile handheld DNA biosensor. Therefore, thorough understandings of the principles behind design of DNA biosensor during biophysical interfacial transduction were explored. The ...

  • A proposition for single molecule DNA sequencing through a nanopore entropic trap

    We propose that a DNA entropic trap constructed from a single resizable nanopore could be tuned in real time to capture a single-stranded polynucleotide. With a nanopore of sufficient discriminatory capability, the trapped polynucleotide will be immobilised within the corrugational trough of an inter-nucleotide separation and the prolonged dwell time will enable scrutiny of the nucleotide ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Design and analysis of nanowire sensor array for prostate cancer detection

    Prostate cancer is one of the major cancer affecting men in India. After lung cancer, prostate cancer has caused large number of deaths in India. Nanowire is the biosensor used for detection of cancer. In this paper, we present a design of nanowire array sensor for prostate cancer detection. A sensor array of 8 × 8 elements is designed to capture the PSA present in the blood that helps in ...

  • Esterase autodisplay: enzyme engineering and whole-cell activity determination in microplates with ph sensors

    Among the GDSL family of serine esterases/lipases is a group of bacterial enzymes that posses C-terminal extensions involved in outer membrane anchoring or translocation. ApeE from Salmonella enterica serovar Typhimurium, a member of this group, has been expressed in Escherichia coli and was resistant to protease digestion when the protease was ...

  • Electrochemical synthesis of polypyrrole for biosensor application

    Polypyrrole nanowires were electrochemically synthesised on platinum electrode at ambient temperature. The potentiostatic potential was set at 0.75 V in the presence of gelatin as soft mould. The whole process only took few hundred seconds. The morphologies, chemical composition and conductivity of nanowires were evaluated by means of Scanning Electron Microscopy (SEM), Fourier Transform Infrared ...

  • Distinct functions of pot1 at telomeres

    The mammalian protein POT1 binds to telomeric single-stranded DNA (ssDNA), protecting chromosome ends from being detected as sites of DNA damage. POT1 is composed of an N-terminal ssDNA-binding domain and a C-terminal protein interaction domain. With regard to the latter, POT1 heterodimerizes with the protein TPP1 to foster binding to telomeric ...

  • Changing views on ionising radiation-induced cellular effects

    Low dose and low dose-rate effects of ionising radiation (IR) are important issues in radiation protection. For these low exposures, radiation-induced double-strand breaks (DSB) and locally multiply damaged sites (LMDS) are considered very deleterious for cells, leading to lethality, mutations, genetic instability and cancer. However, recent results suggest that LMDS are much less frequent than ...

  • Quantum dots and nanostructured conducting polymers for biosensing applications

    Numerous methodologies are currently being employed for the preparation of nanomaterials in customised morphologies. In this paper, we outline recent progress in our laboratory to develop nanostructured inorganic semiconductors – quantum dots (QDs), and nanostructured organic semiconductors based on polyaniline (PANI), for biosensing applications. Blue luminescent CdTe QDs were prepared directly ...

  • Spectral distribution of uv light during aging of medium pressure UV lamps

    As part of a project to validate a UV reactor for disinfection of drinking water, the germicidal output of four medium pressure lamps housed in a continuously operating reactor was followed as a function of time. Spectra were measured monthly and were used in conjunction with radiometer readings to calculate germicidal fluence rates (using DNA absorbance weighting) at the radiometer sensor ...

  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • Introduction to the BioCar Nature Based Transportation Systems

    The people of the world are rapidly growing aware of the full impact of current transport systems upon their safety, economy, health and environment. This has not been lost on the major auto companies who have spent millions of man-hours and billions of dollars over the last decade in pursuit of the Next Generation Vehicle. But they have little to show for their efforts having been increasingly ...
