Spectral engineering via complex patterns of rounded concave and convex nanoresonators achievable via integrated lithography realized by circularly polarized light

Sipos Á., Tóth E., Török A., Fekete O., Szabó G., Csete M., University of Szeged, HU

Comparative study has been performed on the spectral and near-field properties of complex concave and convex nano-object patterns that can be fabricated via interferometric illumination of colloid sphere monolayers (IICSM) by applying circularly polarized light. [...]

Coupled surface plasmon resonance on rotated sinusoidal gratings at different azimuthal orientations

Csete M., Szalai A., Tóth E., Somogyi A., Balázs J., Szabó G., University of Szeged, HU

Theoretical study was performed on rotated grating coupling phenomenon on multilayers comprising 416 nm periodic sinusoidal polymer gratings with 35 nm modulation amplitude aligned on a bimetal film made of gold and silver layers. The [...]

Plasmonic structure integrated single-photon detectors for absorptance and polarization contrast maximization

Csete M., Szenes A., Maráczi D., Bánhelyi B., Csendes T., Szabó G., University of Szeged, HU

Superconducting nanowire single photon detectors (SNSPDs) are important for single-photon detection at 1550 nm infrared wavelength in quantum information processing (QIP), telecommunication and astronomy [1, 2]. Absorptance of single photons with a specific polarization has [...]

Novel nanostructured drug delivery technology to enhance bioavailability, increase solubility and drug loading

Heltovics G., Ötvös Zs., Filipcsei G., Darvas F., NanGenex Inc., HU

In the presentation we will discuss the perspectives and pharmacokinetic benefits of the nanosized active molecules over the parent active molecules. The bioavailability of reference and nanosized drug was determined after oral administration (30 mg/kg) [...]

Mathematical modeling and computer simulation of Brownian motion and hybridization of nanoparticle-bioprobe-polymer complexes in the low concentration limit

Toth A., Banky D., Grolmusz V., Eotvos University, HU

We present a mathematical model and the computer simulation of Brownian motion of nanoparticle-bioprobe-polymer contrast agent complexes and their hybridization to immobilized targets. Our model is a stochastic counterpart of the continuous model presented in [...]

Designing universal oligonucleotides for DNA/nanoparticle conjugates

Ivan G., Grolmusz V., Eotvos Lorand University, HU

As DNA sequences originating from different species are highly specific, it is a challenge to design “universal” DNA/nanoparticle conjugates that are able to hybridize to each member of a set of nucleotide sequences. Possible applications [...]

Novel organic-inorganic nanohybrids based on poly(N,N-dimethyl acrylamide)-l-polyisobutylene amphiphilic polymer conetworks

Mezey P., Domján A., Iván B., Thomann R., Mülhaupt R., Hungarian Academy of Sciences, HU

Poly(N,N-dimethyl acrylamide)-l-polyisobutylene (PDMAAm-l-PIB) amphiphilic conetworks were synthesized. Thermal analysis (DSC), small angle X-ray scattering (SAXS) measurements and atomic force microscopy (AFM) investigations were made. Furthermore, we have successfully synthesized silver nanoparticles in the PDMAAm-l-PIB amphiphilic [...]
