Abstract

This study is aimed at elucidating the physical processes responsible for the excellent spectral qualities in terms of full width at half-maximum (fwhm) and signal-to-noise (S/N) ratio shown in a special double pulse laser-induced spectroscopy. Apart from the use of atmospheric He ambient gas, the achievement is due to the first laser for generating He gas plasma and the subsequent use of the second laser pulse for target ablation, in opposite order of the two-laser operations in conventional double pulse LIBS. This setup allows adjustments of the many experimental parameters to yield the optimal condition resulting in 0.03 nm fwhm and around 1000× S/N ratio of Cu I 521.8 nm and far surpasses the spectral qualities obtained by other techniques. This is obtained by allowing the crucial separation of the target plasma from the He gas plasma and thereby enabling the He-assisted excitation (HAE) to play its full and unique role of nonthermal excitation, taking advantage of metastable excited He atoms in the He plasma and the Penning-like energy transfer process.

ABSTRACT: We fi rst report on constant potential (dc) amperometric fl ow-injection analysis (FIA) transduced by electroactive (conductive) polymers. Amperometric response is caused by the polymer recharging in order to maintain the electrode potential at a constant level when (i) ions are crossing the fi lm | solution interface and polarizing electrode | fi lm interface or (ii) ions or neutral molecules are speci fi cally interacting with the polymer recharging it. The response under constant solution fl ow is a current peak and in fl ow- injection mode is a couple of current peaks directed opposite of the fi rst sharp, analytically valuable peak. In both constant fl ow and fl ow-injection regimes, the peak current is dependent on analyte concentrations; obviously, the FIA mode provides

more advantageous analytical characteristics. Constant potential amperometric ﬂ ow-injection analysis is shown for boronate- and sulfate-functionalized polyanilines as well as for Prussian Blue, a member of the inorganic polymer family. As a proof of concept, the successful dc amperometric detection of lactate in human sweat with boronate-functionalized polyaniline has been shown. The proposed approach would revolutionize the ﬁ eld of conductive/electroactive polymer-supported ion sensing with the introduction of reliable and robust amperometry as a valuable alternative to existing potentiometry.

C onductive polymers since the discovery of polyacetylene

¹

have attracted a great amount of interest of scientists in diﬀerent ﬁelds including analytical chemistry. A search in Web of Science (WoS) for conducting polymer-based sensors returns >6000 citations. Of particular importance is the so- called “ solid contact ” for ion-selective electrodes,

²⁻⁴

also referred to as “ ion-to-electron interface ” .

⁵

In addition to ion-selective electrodes, conductive polymers can also serve as transducers for neutral molecules. Among synthetic receptors, phenylboronic acid is particularly attractive due to binding selectivity to compounds possessing 1,2- or 1,3- diol functionalities, common structural elements of saccharides and hydroxy acids.

⁶⁻⁹

Involving phenylboronic acid in conductive polyaniline, the reagentless sensor which is able to generate an increase in its conductivity as a result of binding with polyols, has been elaborated.

¹⁰

Flow-injection analysis (FIA)

¹¹

is of particular importance providing simple, cost-e ﬀ ective, and express analysis of multiple samples. In addition, FIA protocol involves a transducer washing step after each injection, which is important for its regeneration if it is inhibited by the analyte or the product of its transformation.

The most reliable and robust detection principle for FIA is constant potential (dc) amperometry. However, for conduct- ing (electroactive) polymer-based transducers, this detection

principle has not been reported yet. Despite that the ﬁ rst amperometric FIA of electroinactive ions with conductive polymers was carried out 33 years ago,

¹²

in it and ref 13, potential step techniques were used making the detection scheme voltammetric rather than true amperometric.

The attempts to realize the dc amperometric transduction principle for conductive polymer-supported ion-selective electrodes introduced by Bobacka’s group

¹⁴⁻¹⁶

resulted in coulometric rather than amperometric read-out,

^14,15

most probably, to improve the reproducibility of the chosen batch rather than ﬂ ow-injection mode. However, even integrating amperometric response (coulometric read-out), the only stepwise dilution calibration graphs over a wide concentration range have been obtained.

¹⁵

Stepwise addition for chloride- selective electrode resulted in the extremely narrow calibration range (0.01 − 0.02 M),

¹⁶

obviously hardly applicable for analysis.

Flow-injection analysis is known to provide signi ﬁ cant advantages over batch mode even for amperometry of electroactive compounds reaching steady-state current under

ABSTRACT: Absolute quanti ﬁ cation of ligand capped on the surface of nanoparticles (NPs) has faced a great challenge without the use of complex inner standards (CIS). Herein, we proposed a facile electrophoresis titration (ET) model, designed an ET device, and developed a relevant method for counting the ligand on NPs without the use of CIS, based on moving reaction boundary (MRB). Furthermore, we conducted the relevant ET runs by using 3-mercaptopropionic acid (MPA) and quantum dots (QDs) as the model ligand and NPs, respectively. The experiments revealed that the ligand content of 1518 ± 295 obtained via an ET was close to the one of 1408 ± 117 determined via NMR, validating the ET model. Moreover, the experiments showed fair stability (RSD < 5.62%) and simplicity of ET without the use of CIS. Evidently, the ET model opens a window for facile assay of ligand capped on NPs.

via moving reaction boundary (MRB). Figure 1 and Figure S1 show the NPs-ET model for counting the ligands on the NPs surface. In the ET model, 3-mercaptopropionic acid (MPA) and CdSe/ZnS core−shell QDs are, respectively, used as the model ligand and NPs uniformly immobilized in the channel via polyacrylamide gel (PAG), and the hydroxyl ion in the cathode well is applied as the titrant.
