Metallic nanoparticles in the 10-100 nm size range exhibit a very specific optical response in the visible spectrum. Here we present our work towards possible applications of such particles for the design of highly sensitive and miniaturized biosensors. Fabrication of nanoparticles is discussed, comprising hexagonal arrays of truncated tetrahedrons made by nanosphere lithography (NSL), and nano...

Aerosol particles deposited in the lungs that are not readily soluble in the epithelial lining fluid will be phagocytized by alveolar macrophages (AM). Inside the phagolysosomal vacuole, the constituents of the plasma allow dissolution of a variety of compounds at a higher rate than dissolution in extracellular lung fluids. Chelator concentration and a pH value of about 5 were found to control ...

Many processes during the evolution of protoplanetary disks and planet formation are highly sensitive to sizes dust particles that present in disk: The efficiency accretion disk volatile transport on particles, gravoturbulent instabilities leading planetesimals, or pebbles onto large planetary embryos form giant planets typical examples depend involved. Furthermore, radiative properties like ab...

We propose a novel fast-responding and paintable pressure-sensitive paint (PSP) based on polymer particles, i.e. polymer-particle (pp-)PSP. As a fast-responding PSP, polymer-ceramic (PC-)PSP is widely studied. Since PC-PSP generally consists of titanium (IV) oxide (TiO₂) particles, a large reduction in the luminescent intensity will occur due to the photocatalytic action of TiO₂. We propose the...

Magnetopneumography is the study of the remanent magnetism of foreign intrathoracic ferromagnetic particles after magnetization by an external magnetic field. Given knowledge of the magnetic characteristics of the inhaled particles, this highly sensitive and non-invasive technique allows the measurement of lung dust loads. Many groups of workers have been examined in this way, e.g. welders, coa...

We present a model system in which to study natural selection in the colloid world. In the assembly of active Janus particles into rotating pinwheels when mixed with trace amounts of homogeneous colloids in the presence of an AC electric field, broken symmetry in the rotation direction produces spiral, chiral shapes. Locked into a central rotation point by the centre particle, the spiral arms a...

Many types of biosensors employ magnetic nanoparticles (diameter = 5-300 nm) or magnetic particles (diameter = 300-5,000 nm) which have been surface functionalized to recognize specific molecular targets. Here we cover three types of biosensors that employ different biosensing principles, magnetic materials, and instrumentation. The first type consists of magnetic relaxation switch assay-sensor...

The preparation of monodisperse nanoparticles with uniform size, shape and composition has been intensively pursed because of their scientific and technological interests [1-4]. The major advantage of monodisperse particles may be attributed to the uniform properties of individual particles, which makes the property of whole particles strictly controllable. They have been widely used in industr...

Article history: Received 10 November 2016 Received in revised form 5 January 2017 Accepted 9 January 2017 Available online xxxx Editor: A. Ringwald In this paper we argue that monojet and monophoton searches can be a sensitive test of very highly ionizing particles such as particles with charges 150e and more generally particles that do not reach the outer parts of the detector. 8 TeV monojet ...

Purified defective interfering (DI) particles of vesicular stomatitis virus (VSV) inhibit the replication of a heterologous virus, pseudorabies virus (PSR), in hamster (BHK-21) and rabbit (RC-60) cell lines. In contrast to infectious B particles of VSV, UV irradiation of DI particles does not reduce their ability to inhibit PSR replication. However, UV irradiation progressively reduces the abil...
