Smart Modulators Based on Electric Field-Triggering of Surface Plasmon-Polariton for Active Plasmonics.

Design and properties of a plasmonic modulator in situ tunable by electric field are presented. Our design comprises the creation of periodic surface pattern on the surface of an elastic polymer supported by a piezo-substrate by excimer laser irradiation and subsequent selective coverage by silver by tilted angle vacuum evaporation. The structure creation was confirmed by AFM and FIB-SEM techniques.

Two Cases of Non-fatal Intoxication with a Novel Street Hallucinogen: 3-Methoxy-Phencyclidine.

3-Methoxy-phencyclidine (3-MeO-PCP) is a structural derivative of the dissociative hallucinogen phencyclidine (PCP). Although PCP toxicity is well documented, little is known about this new psychoactive substance despite being available on the black market even in central Europe. The objective of this case report is to present clinical and laboratory data of analytically confirmed non-fatal intoxication of two subjects with 3-MeO-PCP.

Smart Component for Switching of Plasmon Resonance by External Electric Field.

A new approach for preparation of active plasmonic component with capability to switch on/off localized surface plasmon resonance (LSPR) by piezoelectric effect is described. Polyvinylidene fluoride (PVDF) was patterned by polarized KrF excimer laser beam. The polarization was perpendicular to polymer orientation introduced during the poling procedure.

Silver release and antimicrobial properties of PMMA films doped with silver ions, nano-particles and complexes.

Materials prepared on the base of bioactive silver compounds have become more and more popular due to low microbial resistance to silver. In the present work, the efficiency of polymethylmethacrylate (PMMA) thin films doped with silver ions, nanoparticles and silver-imidazole polymer complex was studied by a combination of AAS, XPS and AFM techniques. The biological activities of the proposed materials were discussed in view of the rate of silver releasing from the polymer matrix.
