Highly Sensitive Broadband Raman Sensing of Antibiotics in Step-Index Hollow-Core Photonic Crystal Fibers
Broadband fiber enhanced Raman spectroscopy (FERS) in aqueous media is introduced in elaborated hollowcore photonic crystal fibers. The high requirements on the filigree fiber structure were thoroughly...
PublicationsPhotonic crystal fiber interferometer coated with a PAH/PAAnanolayer as humidity sensor
In this paper, an optical fiber interferometric humidity sensor is presented. The device consists of 1 cm-long segment of photonic crystal fiber (PCF) spliced to standard single mode fibers (SMFs), forming...
PublicationsCharacterization of plasmonic and thermo-optical parameters of spherical metallic nanoparticles
The metallic nanoparticles are widely applied recent years as photothermal agents in laser and optical nanotechnology for light-to-heat conversion, treatment of materials containing NPs, laser nanomedicine,...
PublicationsHybrid-Mode-Assisted Long-Distance Excitation of Short-Range Surface Plasmons in a Nanotip-Enhanced Step-Index Fiber
We propose and experimentally demonstrate a monolithic nanowire-enhanced fiber-based nanoprobe for the broadband delivery of light (550−730 nm) to a deep subwavelength scale using short-range surface...
PublicationsA new strategy for silver deposition on Au nanoparticles with the use of peroxidase-mimicking DNAzyme monitored by Localized Surface Plasmon Resonance technique
Peroxidase-mimicking DNAzyme was applied as a catalyst of silver deposition on gold nanoparticles. This DNAzyme is formed when hemin binds to the G-quadruplex-forming DNA sequence. Such a system is capable...
PublicationsLight-absoption selection of nanoparticles and nanofluids containing nanoparticles for their effective heating by solar radiation
Light-absorption selection of single nanoparticle for solar radiation requires the simultaneous fulfillment of all of the following novel conditions—maximal close (overlap) of the dependence of nanoparticle...
PublicationsResonance-enhanced multi-octave supercontinuum generation in antiresonant hollow-core fibers
Ultrafast supercontinuum generation in gas-filled waveguides is one enabling technology for many intriguing application ranging from attosecond metrology towards biophotonics, with theamount of spectral...
PublicationsAnalysis of nanogap-induced spectral blue-shifts of plasmons on fiber-integrated gold, silver and copper nanowires
We analyze the properties of HE2 surface plasmon polaritons on fiber-integrated gold, silver and copper nanowires and find a systematic blue-shift of the measured resonance wavelengths which we attribute...
PublicationsChemical and Electrochemical Synthesis of Platinum Black
We present electrochemical and chemical synthesis of platinum black at room temperature in aqueous and non-aqueous media. X-ray analysis established the purity and crystalline nature. The electron micrographs...
PublicationsDual-scattering near-field microscope for correlative nanoimaging of SERS and electromagnetic hotspots
Surface-enhanced Raman spectroscopy (SERS) enables sensitive chemical studies and materials identification, relying on electromagnetic (EM) and chemical-enhancement mechanisms. Here we introduce a tool...
