A review on nanostructure-based mercury (II) detection and monitoring focusing on aptamer and oligonucleotide biosensors. Talanta 2020; 220:121437. [PMID: 32928439 DOI: 10.1016/j.talanta.2020.121437] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 07/11/2020] [Accepted: 07/19/2020] [Indexed: 02/08/2023]
Abstract
Heavy metal ion pollution is a severe problem in environmental protection and especially in human health due to their bioaccumulation in organisms. Mercury (II) (Hg2+), even at low concentrations, can lead to DNA damage and give permanent harm to the central nervous system by easily passing through biological membranes. Therefore, sensitive detection and monitoring of Hg2+ is of particular interest with significant specificity. In this review, aptamer-based strategies in combination with nanostructures as well as several other strategies to solve addressed problems in sensor development for Hg2+ are discussed in detail. In particular, the analytical performance of different aptamer and oligonucleotide-based strategies using different signal improvement approaches based on nanoparticles were compared within each strategy and in between. Although quite a number of the suggested methodologies analyzed in this review fulfills the standard requirements, further development is still needed on real sample analysis and analytical performance parameters.

Abstract
To facilitate the implementation of biosensors based on the localized surface plasmon resonance (LSPR) of metal nanostructures, there is a great need for cost-efficient, flexible, and tunable methods for producing plasmonic coatings. Due to its simplicity and excellent conformity, electroless plating (EP) is well suited for this task. However, it is traditionally optimized to produce continuous metal films, which cannot be employed in LSPR sensors. Here, we outline the development of an EP strategy for depositing island-like silver nanoparticle (NP) films on glass with distinct LSPR bands. The fully wet-chemical process only employs standard chemicals and proceeds within minutes at room temperature. The key step for producing spread-out NP films is an accelerated ripening of the silver seed layer in diluted hydrochloric acid, which reduces the nucleation density during plating. The reaction kinetics and mechanisms are investigated with scanning (transmission) electron microscopy (SEM/STEM), X-ray photoelectron spectroscopy (XPS), and UV-vis spectroscopy, with the latter enabling a convenient live monitoring of the deposition, allowing its termination at a stage of desired optical properties. The sensing capabilities of chemically deposited NP films as LSPR transducers are exemplified in DNA biosensing. To this end, a sensing interface is prepared using layer-by-layer (LbL) buildup of polyelectrolytes (PE), followed by adsorption and covalent immobilization of ssDNA. The obtained LSPR transducers demonstrate robustness and selectivity in sensing experiments with binding complementary and unrelated DNA strands.

Abstract
Electrochemical-total internal reflection ellipsometry (EC-TIRE) has been proposed as a technique to observe the redox reactions on the electrode surface due to its high phase sensitivity to the electrolyte/electrode interface. In this paper, we mainly focus on the influence of the potential modulation on the TIRE response. The analysis suggests that both dielectric constant variation of gold and the electric double layer transformation would modulate the reflection polarization of the surface. For a nonfaradaic process, the signal of TIRE would be proportional to the potential modulation. To testify the analysis, linear sweep voltammetry and open circuit measurement have been performed. The results strongly support the system analysis.

Abstract
The adsorption of DNA/Ca(2+), DNA/Cu(2+), and DNA/Co(NH3)6(3+) complexes on amino and silica chip surfaces were investigated using dual polarization interferometry. A more compact DNA/cation complex layer formed on the amino chip surface compared with that on the silica chip surface at the same cation condition. The real-time mass, thickness, and density changes were monitored during the adsorption process. The overall results show that the approaching complexes can cause the conformation rearrangement of the preadsorbed complexes and the preadsorbed complexes affect the deposition pattern of the approaching complexes during the adsorption of DNA/Ca(2+) and DNA/Cu(2+) complexes on both chip surfaces. The relatively strong electrostatic repulsion between the approaching and adsorbed complexes results in multiple mass loading rate changes and loose attachment of the approaching complexes. The weak repulsion between the DNA/Co(NH3)6(3+) complexes cannot induce this kind of conformation rearrangement. Thus, no multiple mass loading rate changes were observed. Meanwhile, the preadsorbed DNA/Co(NH3)6(3+) complex can also affect the deposition pattern of the approaching complex because of the geometric resistance. Therefore, this study will help better understand the conformation change and deposition pattern of complexes with different charge conditions during the adsorption process on the solid-liquid interface.

Abstract
Total internal reflection ellipsometry (TIRE) has been applied for the investigation of (i) kinetics of biosensing layer formation, which was based on the immobilization of fragmented and intact antibodies, and (ii) kinetics of antigen interaction with the immobilized antibodies. It has been demonstrated that ellipsometric parameter Δ(t) showed much higher sensitivity at the initial phase of Au-protein and protein-protein interaction, while the parameter Ψ(t) was more sensitive when the steady-state conditions were established. A new method, which taking into consideration this feature and nonlinear change of Δ(t) and Ψ(t) parameters during various stages of biological layer formation process, was used for the calculation of antibody and antigen adsorption/interaction kinetics. The obtained results were analyzed using a model, which took into account partial reversibility during the formation of both antibody and antigen based monolayers. It was shown that the immobilization rate of antibody during the preparation of the sensing layer was similar for the formation of both intact and fragmented antibody based layers; however, the residence time was 25 times longer for intact antibody based layer formation in comparison to that of fragmented antibody based layer formation. On the contrary, residence time of antigen interaction with immobilized antibodies was about 8 times longer for the sensor based on fragmented antibodies. Moreover, it has been determined that the structural differences of immobilized antibodies (fragmented or intact) significantly influence antibody-antigen interaction rate, the major difference being in the residence time of antigen interaction with both types of immobilized antibodies.

Abstract
This work describes a detailed quantitative interaction study between the novel plastidial chaperone receptor OEP61 and isoforms of the chaperone types Hsp70 and Hsp90 using the optical method of total internal reflection ellipsometry (TIRE). The receptor OEP61 was electrostatically immobilized on a gold surface via an intermediate layer of polycations. The TIRE measurements allowed the evaluation of thickness changes in the adsorbed molecular layers as a result of chaperone binding to receptor proteins. Hsp70 chaperone isoforms but not Hsp90 were shown to be capable of binding OEP61. Dynamic TIRE measurements were carried out to evaluate the affinity constants of the above reactions and resulted in clear discrimination between specific and nonspecific binding of chaperones as well as differences in binding properties between the highly similar Hsp70 isoforms.

Abstract
Poly(methyl methacrylate) (PMMA) flow-cells containing microwells were deposited with different nonspecific binding blocking agents, namely, bovine serum albumin (BSA), cationic lipid (DOTAP:DOPE) and diethylene glycol dimethyl ether (DEGDME). Water contact angle (WCA) and atomic force microscope (AFM) measurements were carried out to confirm the successful depositions of BSA, DOTAP, and DEGDME onto the PMMA surfaces. Fluorescent intensity measurements were performed to evaluate the degree of nonspecific adsorption of Cy5-labeled anti-IgG proteins onto plain and oxygen plasma-treated (PT) PMMA flow-cells as well as PMMA flow-cells deposited with different above-mentioned blocking agents. We then employed a label-free detection method called total internal reflection ellipsometry (TIRE) to evaluate the stability of the deposited blocking agents inside the PMMA flow-cells. It was found that, while DOTAP:DOPE was the best agent for blocking the nonspecific adsorption, it could be removed from the PMMA surfaces of the flow-cells upon rinsing with phosphate buffered saline (PBS) and later deposited back onto the Au-coated glass sensing substrate of the TIRE. The removal of the blocking agents from PMMA surfaces and their deposition onto the sensing substrate were further manifested by measuring the kinetics and the amount of adsorbed anti-α-hCG proteins. Overall, the dry DEGDME coating by plasma-enhanced chemical vapor deposition (PECVD) showed very good blocking and excellent stability for subsequent assay inside the microwells. Our results could be useful when one considers what blocking agents should be used for PMMA-based microfluidic immunosensor or biosensor devices by looking at both the blocking efficiency and the stability of the blocking agent.

Abstract
The detection and characterization of the hybridization event of 21-base, unlabeled DNA oligonucleotides with a monolayer of complementary DNA immobilized on a gold surface, by electrochemical impedance spectroscopy and surface plasmon resonance (SPR) is presented. A thiol modification on the probe DNA strand allowed for its attachment to the surface via self-assembly. For the hybridization of full match target DNA a detection limit of 20 pM was determined. RNA hybridization was also detectable with the same sensor, with a similar detection limit. The SPR signal generated upon hybridization of the full match was always distinguishable from the single mismatch target DNA oligonucleotides when the mismatch was in the middle or at the proximal end of the target DNA sequence. However, the response of the sensor was identical for the hybridization of the full match and the distal end mismatch. The SPR sensor described is reusable over at least 20 hybridization/regeneration cycles and is insensitive to flow rate (20-800 µL min-1) or temperature (20-60 °C). Based on the SPR response, the surface density of the probe was estimated to be at least 4.3 × 1012 molecules per cm2.

Abstract
In this chapter, the basic concepts behind ellipsometry and spectroscopic ellipsometry are discussed along with some instrument details. Ellipsometry is an optical technique that measures changes in the reflectance and phase difference between the parallel (RP) and perpendicular (RS) components of a polarized light beam upon reflection from a surface. Aside from providing a simple, sensitive, and nondestructive way to analyze thin films, ellipsometry allows dynamic studies of film growth (thickness and optical constants) with a time resolution that is relevant to biomedical research. The present chapter intends to introduce ellipsometry as an emerging but highly promising technique, that is useful to elucidate the interactions of proteins with solid surfaces. In this regard, particular emphasis is placed on experimental details related to the development of biomedically relevant conjugated surfaces. Results from our group related to adsorption of proteins to nanostructured materials, as well as results published by other research groups, are discussed to illustrate the advantages and limitations of the technique.
