Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Nanoparticles in analytical laser and plasma spectroscopy – a review of recent developments in methodology and applications

“…It was shown, that the material and surface concentration of NPs, as well as the laser wavelength and irradiance all have a great impact on the signal enhancement achievable. 12,550 The production of the plasma plays a crucial role in LIBS. In general, the plasma induction needs the production of free electrons, the so-called seed electrons.…”

“…550 Modied SERS substrates consisting of Ag NPs on indium-tin-oxide glass were also used for quantitative NELIBS measurements on liquid solutions of Mn, Zn and Cr, and it was found that interparticle distance plays crucial role in efficient enhancement. 12 A biological sample was used as subject in the rst demonstration of the NELIBS effect. A colloidal silver solution was applied to a leaf surface 469 allowing the measurements of several alkaline metals with an enhancement of about a factor of 5.…”

“…He is a full professor and the head of the Department of Inorganic and Analytical Chemistry at the University of Szeged since 2014. contributes to or provides inspiration for the development of new ones. Among others, sample preparation and separation techniques, 4,5 chemical sensing [6][7][8] and spectroscopy [9][10][11][12] are the elds of analytical science that have the most interaction with nanoscience. Instrumental analytical techniques are also crucial to the characterization of NPs, 13 as well as for the monitoring of nanostructures either during controlled synthesis 14,15 or when released in the environment.…”

“…Analytical signal enhancement in LPS is also oen effectuated by using nanoparticles, mostly based on plasmonic effects. A premier example for this is surface enhanced Raman spectroscopy (SERS), 10 but LA-ICP-MS 40 and LIBS 12,41 applications are also beneting from similar effects. Last, but not least, the use of NPbased liquid sample preparation methodologies in LPS in Attila Kohut completed his PhD in physics at the University of Szeged, Hungary in 2018.…”

Application of Bacteriophages in Nanotechnology

“…Phages can be used for designing surface-enhanced Raman scattering (SERS) sensors by implementing phage display with the noble metal-binding motif. SERS sensors are usually based on nanostructured silver or gold surfaces [ 167 , 168 , 169 ]. The nanoarchitecture of those metals enhances the electromagnetic field of excitation light, which amplifies the signal from the analyte.…”
