(2011)A novel electronic nose device is presented that can be used in disease diagnostics by exhaled breath analysis. Exhaled breath contains more than a thousand organic compounds that can be analysed to insect various diseases ... -
Biosensors for early disease diagnosis
(John Wiley & Sons, 2016-03-11)This chapter focuses on biosensor types, their detection limits, analysis times, and the diseases they are suitable for detecting. In addition, as nanomaterials are an effective means of producing small‐scale diagnostic ... -
Bismuth nano-Hall probes fabricated by focused ion beam milling for direct magnetic imaging by room temperature scanning Hall probe microscopy
(The Institution of Engineering and Technology (IET), 2001)Bismuth nano-Hall probes fabricated by using focused ion beam (FIB) milling were studied. The nano-Hall probes were used for direct magnetic imaging of domain structures in low coercivity garnets and demagnetized strontium ... -
Charge Trapping Memory with 2.85-nm Si-Nanoparticles Embedded in HfO2

Chiral single-wall gold nanotubes
(American Physical Society, 2004)The formation of freestanding and tip-suspended chiral-wall (n,m) nanotubes, which were composed of helical atomic strands, from gold atoms was investigated using first-principles calculations, where (n,m) notation defines ... -
A comparative study of O2 adsorbed carbon nanotubes
(2003)First-principles, density functional calculations show that O2 adsorbed single-wall carbon nanotubes (SWNT) show dramatic differences depending on the type of the tube. Upon O2 physisorption, the zig-zag SWNT remains ... -
Conjugated polymer nanoparticles for cell labelling, imaging and drug delivery
(European Association for Chemical and Molecular Sciences, 2012-08)Nanoparticles based on conjugated polymers are emerging as a new class of luminescent nanoparticles. These nanoparticles have many potential applications including imaging agents, biosensors, and photonics owing to their ... -
Cyclodextrin nanofibers by electrospinning
(Royal Society of Chemistry, 2010)We have demonstrated that cyclodextrin (CD) (a non-polymeric system) can be electrospun into nanofibers by itself; methylbeta-cyclodextrin (MbCD) nanofibers were electrospun and it was observed that the success of the ... -
Differential immune activation following encapsulation of immunostimulatory CpG oligodeoxynucleotide in nanoliposomes
(Elsevier, 2011)The immunogenicity of a vaccine formulation is closely related to the effective internalization by the innate immune cells that provide prolonged and simultaneous delivery of antigen and adjuvant to relevant antigen ... -
Dynamic thread and data mapping for NoC based CMPs
(IEEE, 2009-07)Thread mapping and data mapping are two important problems in the context of NoC (network-on-chip) based CMPs (chip multiprocessors). While a compiler can determine suitable mappings for data and threads, such static ... -
The effect of gadolinium doping on the structural, magnetic and photoluminescence properties of electrospun bismuth ferrite nanofibers
(Elsevier Ltd, 2015)Gadolinium (Gd) doped Bismuth ferrite (BFO) nanofibers (Bi1-xGdxFeO3 (x=0.0, 0.05, 0.10, 0.15 and 0.20)) were synthesized via electrospinning. Scanning Electron Microscope (SEM) analysis showed that the diameter of the ... -
