The GCE surface was modified using a simple drop-casting technique with a PtNPs/MWCNT composite, and the composite was subsequently characterized by UV–Vis and FTIR spectroscopy, XRD, FESEM-EDS, and TEM techniques. The highest sensitivity of the developed sensor was achieved when the optimum composition of PtNPs and MWCNT was 4:6 on the surface of the GCE. This phenomenon may be attributed to the synergistic interaction between PtNPs and MWCNTs, which enhances the conductivity of the modified electrodes. The synergistic effect in relation to the catalytic activity of PtNPs and the large electroactive surface area of MWCNT results in an enhanced electrocatalytic signal for sensing purposes. Concurrently, the analytical performance of PtNPs/MWCNT/GCE was investigated using the differential pulse voltammetry (DPV) technique, which showed a linear response for HQ and MP in the ranges of 5–200 μM and 50–500 μM, respectively. Moreover, this proposed sensor demonstrated a low limit of detection and good sensitivity for the simultaneous detection of HQ (0.4 μM and 1.8136 μA μM<sup>−1</sup> cm<sup>−2</sup>) and MP (0.8 μM and 0.7076 μA μM<sup>−1</sup> cm<sup>−2</sup>).

In this work, optimal geometric parameters of the transceiving channel of the lidar optical system are chosen, a need to focus laser radiation at a distance of 1 km from an observation point is demonstrated, and numerical simulations confirm the possibility of detecting lidar signals ranging from 10<sup>−7</sup> to 10<sup>−10</sup> W in the informative spectral range 4800–5100 cm<sup>−1</sup> (1960–2083 nm). Laboratory experiments with the main components of the lidar system with experimentally confirmed parameters, which simulate atmospheric measurements of CO<sub>2</sub> absorption at a calibrated sensing wavelength of 2005 nm (4987 cm<sup>−1</sup>) (pressure of 1 atm; CO<sub>2</sub> concentration corresponding to the midlatitude summer background atmosphere) in the informative spectral range of the lidar system, enable selecting a pair of wavelengths with resonant absorption of the target gas near 2005 nm to study the background state of the atmosphere in the surface layer. Efficiency of the lidar optical system is confirmed by in situ test experiments, where backscattering signals from a topographic target with an albedo of ∼0.15 spaced 168 m apart from an observer are recorded at 60 mV when operating along a horizontal atmospheric path.

Clinicians can make important decisions with the aid of quick analysis and quantification, ideally at the patient's bedside. Electrochemical immunosensors are effective point-of-care technologies to address these issues. Here, we describe the development of a simple electrochemical immunosensor to detect DD. The immunosensor is constructed by electrodeposition of lactose methoxide aniline silver nanoparticles (LMA-AgNPs) on a screen-printed carbon electrode (SPCE). The LMA-AgNP and SPCE/LMA-AgNP were characterized by Fourier transform infrared (FTIR) spectroscopy, high-resolution transmission electron microscopy (HR-TEM), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), and X-ray photoelectron spectroscopy (XPS). The electrochemical behavior of the SPCE/LMA-AgNP was examined using electrochemical impedance spectroscopy (EIS), differential pulse voltammetry (DPV), and cyclic voltammetry (CV). Then, Anti-D-Dimer antibody (Anti-DD) was immobilized on SPCE/LMA-AgNP. Along with the analytical characterization of the SPCE/LMA-AgNP/Anti-DD immunosensor, the linear range for DD, limit of detection (LOD), potential chemical interferences, and real sample applications were also evaluated. The antigen/antibody interaction at various DD concentrations was monitored using DPV. The SPCE/LMA-AgNP/Anti-DD shows a linear response in the DD concentration range of 0.01–1 pg/mL and a LOD of 0.2 fg/mL. In addition, the SPCE/LMA-AgNP/Anti-DD showed excellent specificity and no response to potential interfering substances, for instance urea, insulin, C-reactive protein (CRP), and serum amyloid A (SAA).
