Performance limits of single nano-object detection with optical fiber tapers

Detecting the scattering process of individual nanoobjects using optical fibers is a promising fast, reliable and label-free detection scheme with strong potential in fields such as bioanalytics or disease...

Tuning light concentration inside plasmonic core-shell nanoparticles during laser irradiation

Computer modeling was carried out of the intensity distributions of optical (laser) radiation with wavelengths in the range of 180 - 540 nm concentrated inside spherical two-layered core-shell nanoparticles...

Biomimetic mineralization can increase the crystallinity of enamel and dentin

Objective. Since enamel is not capable of regeneration and dentin repair is dependent on odontoblasts and is directed towards the pulp, current treatment options aim to seal or fill these lesions. Previous...

Nanowire-based hybrid optical fibers: a platform for nonlinear light generation, nanoscale plasmonics and single nanoobject detection

Plasmonics for Nanoscale Light-matter Interaction

Well-designed plasmonic nanostructures can concentrate and control optical fields at nanometer scale [1] and provide stiff optical potential to manipulate nanoobjects [2]. Recently, it has been shown that...

Isolation and Spectroscopic Detection of Single Tumor Cells Using Surface- Enhanced Raman Nanoparticles Tags

Nowadays, cancer is one of the most dangerous and deadly disease all around the world. Cancer that is diagnosed at early stages is more likely to be treated successfully. Treatment of progressed cancer...

A droplet-based microfluidic chip as a platform for leukemia cell lysate identification using surface enhanced Raman scattering

A new approach is presented for cell lysate identification which uses SERS-active silver nanoparticles and a droplet-based microfluidic chip. Droplets are generated by injecting silver nanoparticles, KCl...

Evaluation of Shifted Excitation Raman Difference Spectroscopy and Comparison to Computational Background Methods Applied to Biochemical Spectra

Raman spectroscopy provides label-free biochemical information from tissue samples without complicated sample preparation. The clinical capability of Raman spectroscopy has beendem onstrated in a wide...

SQUID based magnetic full tensor gradiometer for maritime application

A new system for submarine application of cryo-cooled SQUID (superconducting quantum interference device) is introduced. Those sensors are mounted on a towed underwater platform and allow the passive measurement...

Efficient and high resolution geomagnetic prospection based on SQUID technology

Geomagnetic prospection is a non-invasive geophysical method for the efficient investigation of large areas. This beneficial and contact-free method acquires Earth’s magnetic field components and their...
