Abstract
We report a platform utilizing a reporter enzyme, which produces a chromogenic indigo precipitate that preferentially localizes within a hydrogel microparticle. The 3D network of the hydrogel maintains the rapid target binding kinetics found in solution, while multiplexed target detection is achieved through shape-encoding of the particles. Moreover, the precipitate-laden hydrogels can be imaged with a simple phone camera setup. We used this system to detect microRNA (miRNA) down to 0.22 fmol. We then showed the compatibility of this system with real samples by performing multiplexed miRNA measurements from total RNA from matched colon cancer and normal adjacent tissue.

Towards the Development of a 3-D Biochip for the Detection of Hepatitis C Virus. SENSORS 2020; 20:s20092719. [PMID: 32397590 PMCID: PMC7249126 DOI: 10.3390/s20092719] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/06/2020] [Accepted: 05/06/2020] [Indexed: 02/06/2023]
Abstract
The early diagnostics of hepatitis C virus (HCV) infections is currently one of the most highly demanded medical tasks. This study is devoted to the development of biochips (microarrays) that can be applied for the detection of HCV. The analytical platforms of suggested devices were based on macroporous poly(glycidyl methacrylate-co-di(ethylene glycol) dimethacrylate) monolithic material. The biochips were obtained by the covalent immobilization of specific probes spotted onto the surface of macroporous monolithic platforms. Using the developed biochips, different variants of bioassay were investigated. This study was carried out using hepatitis C virus-mimetic particles (VMPs) representing polymer nanoparticles with a size close to HCV and bearing surface virus antigen (E2 protein). At the first step, the main parameters of bioassay were optimized. Additionally, the dissociation constants were calculated for the pairs “ligand–receptor” and “antigen–antibody” formed at the surface of biochips. As a result of this study, the analysis of VMPs in model buffer solution and human blood plasma was carried out in a format of direct and “sandwich” approaches. It was found that bioassay efficacy appeared to be similar for both the model medium and real biological fluid. Finally, limit of detection (LOD), limit of quantification (LOQ), spot-to-spot and biochip-to-biochip reproducibility for the developed systems were evaluated.

Abstract
A covalent conjugate of horseradish apoperoxidase and amino-containing oligonucleotide was synthesized for the first time. Using the obtained conjugate as a capture reagent chemiluminescent microtiter plate-based assay for detection of 35-mer fragment of hepatitis B virus (HBV) DNA (proof-of-concept analyte) was developed. To detect the target DNA, a signaling system consisted of biotinylated reporter oligonucleotide and HRP-streptavidin conjugate was used. The high sensitivity of the assay was due to the enhanced chemiluminescence reaction, where 3-(10′-phenothiazinyl)propane-1-sulfonate/N-morpholinopyridine pair was used as an enhancer. Under the optimized conditions the limit of detection and a working range of the assay were 3 pM and 6⁻100 pM, respectively. The assay sensitivity was 1.6 × 10⁵ RLU/pM of target. The coefficient of variation (CV) for determination of HBV DNA within the working range was lower than 6%.

Abstract
A colorimetric microarray for the multiplexed detection of recurrence of bladder cancer including protein markers interleukin-8 (IL8), decorin (DCN), and vascular endothelial growth factor (VEGF) was established to enable easy and cheap read-out by a simple office scanner paving the way for quick therapy monitoring at doctors' offices. The chip is based on the principle of a sandwich immunoassay and was optimized prior to multiplexing using IL8 as a model marker. Six different colorimetric assay formats were evaluated using a detection antibody (dAB) labeled with (I) gold (Au) nanoparticles (NPs), (II) carbon NPs, (III) oxidized carbon NPs, and a biotinylated dAB in combination with (IV) neutravidin-carbon, (V) streptavidin (strp)-gold, and (VI) strp-horseradish peroxidase (HRP). Assay Format (III) worked best for NP-based detection and showed a low background while the enzymatic approach, using 3,3',5,5'-tetramethylbenzidine (TMB) substrate, led to the most intense signals with good reproducibility. Both assay formats showed consistent spot morphology as well as detection limits lower than 15 ng/L IL8 and were thus applied for the multiplexed detection of IL8, DCN, and VEGF in synthetic urine. Colorimetric detection in urine (1:3) yields reaction signals and measurement ranges well comparable with detection in the assay buffer, as well as excellent data reproducibility as indicated by the coefficient of variation (CV 5-9%).

Abstract
Analysis of variations in DNA structure using a low-density microarray technology for routine diagnostic in evidence-based medicine is still relevant. In this work the applicability of 3-D macroporous monolithic methacrylate-based platforms for detection of different pathogenic genomic substitutions was studied. The detection of nucleotide replacements in F5 (Leiden G/A, rs6025), MTHFR (C/T, rs1801133) and ITGB3 (T/C, rs5918), involved in coagulation, and COMT (C/G, rs4818), TPH2 (T/A, rs11178997), PON1 (T/A rs854560), AGTR2 (C/A, rs11091046) and SERPINE1 (5G/4G, rs1799889), associated with pregnancy complications, was performed. The effect of such parameters as amount and type of oligonucleotide probe, amount of PCR product on signal-to-noise ratio, as well as mismatch discrimination was analyzed. Sensitivity and specificity of mutation detections were coincided and equal to 98.6%. The analysis of SERPINE1 and MTHFR genotypes by both NGS and developed microarray was performed and compared.

Abstract
The present study describes the development, optimization and performance comparison of three ELISAs and one multiplex immunoassay in a microarray format. The developed systems were dedicated to the detection of three different classes of pollutants (pesticide, explosive and toxin) in water. The characteristics and performances of these two types of assays were evaluated and compared, in order to verify that multiplex immunoassays can replace ELISA for multiple analyte sensing. 2,4-Dichlorophenoxyacetic acid, 2,4,6-trinitrotoluene and okadaic acid were chosen as model targets and were immobilized in classical microtiter plate wells or arrayed at the surface of a microarray integrated within a classical 96-well plate. Once optimized, the classical ELISAs and microarray-based ELISA performances were evaluated and compared in terms of limit of detection, IC50, linearity range and reproducibility. Classical ELISAs provided quite good sensitivity (limit of detection down to 10 μg L(-1)), but the multiplex immunoassay was proven to be more sensitive (limit of detection down to 0.01 μg L(-1)), more reproducible and an advantageous tool in terms of cost and time expenses. This multiplex tool was then used for the successful detection of the three target molecules in spiked water samples and achieved very promising recovery rates.

Abstract
The usability of many high-throughput lab-on-a-chip devices in point-of-care applications is currently limited by the manual data acquisition and analysis process, which are labor intensive and time consuming. Based on our original design in the biochemical reactions, we proposed here a universal approach to perform automatic, fast, and robust analysis for high-throughput array-based microfluidic immunoassays. Inspired by two-dimensional (2D) barcodes, we incorporated asymmetric function patterns into a microfluidic array. These function patterns provide quantitative information on the characteristic dimensions of the microfluidic array, as well as mark its orientation and origin of coordinates. We used a computer program to perform automatic analysis for a high-throughput antigen/antibody interaction experiment in 10 s, which was more than 500 times faster than conventional manual processing. Our method is broadly applicable to many other microchannel-based immunoassays.

Abstract
This report describes a straightforward approach for the achievement of sub-100 micrometers size hydrogel dots supporting DNA immobilization. Hydrogel-DNA spots are arrayed and UV-crosslinked on PolyShrink, an innovative polymer material having the remarkable property of isotropically shrinking under high temperature. Curing the microarray enables then spot miniaturization, resulting in 6 µm thick and 60 µm wide hydrogel dots in which oligonucleotides are immobilized in a 3D hydrophilic environment. The probe immobilization within the hydrogel network and its capacity to detect targets specifically and quantitatively is demonstrated using chemiluminescent as well as colorimetric detection techniques. The hydrogel material improves probe accessibility within the spot, leading to an enhanced sensitivity.

Abstract
The present report describes the integration and application possibilities of a new microarray concept based on adhesive surface. The method was shown to enable the straightforward production of 384 and 1536-well plates modified with 100 and 25 spots per well, respectively. Such in-well densities were only possible thanks to the fabrication process which implies first the deposition of the microarray on a flat adhesive surface and then its assembly with bottomless 384 or 1536-well plates. The concept was also confronted to various applications such as oligonucleotide detection, localised cell culture onto spotted adhesion proteins and immobilisation of peptide or active antibodies for immunoassays. In the particular case of immunotesting, the study focused on liver diseases diagnosis and more particularly on the detection of either one liver cancer marker, the alpha-fetoprotein, or the detection of Hepatitis C Virus infection. In every cases, interesting performances were obtained directly in crude patient serum, proof of the robust and generic aspect of the platform.
