Abstract
The development of a sensitive and isothermal technique with a greatly enhanced miRNA detection signal is still technically problematic due to the low abundance of miRNA and high sequence similarities with homologous miRNAs. Herein, we propose a novel fluorescence approach for sensitive and reliable miRNA detection by integrating the palindrome sequence mediated target recycling with self-priming assisted signal reaction. In this method, a dual toehold DNA nano-probe (HT) with two functional arms is designed to mediate specific target recognition and signal amplification. In the presence of target miRNA, it binds to the recognition module of HT probe, releasing the "2" sequence to initiate strand displacement amplification (SDA) and a self-priming-induced signal reaction. Based on the elegant design, the proposed method exhibits a wide linear response range exceeding five orders of magnitude and a low limit of detection of 0.96 fM according to the 3δ rule. The non-specific signal is below 5 % for non-target miRNA detection. Taking the merits of excellent sensitivity, desirable specificity, and superior anti-interference ability, the proposed approach shows a promising prospect for detecting miRNAs in complicated biological environments and early diagnosis of diseases.

Highly sensitive photoelectrochemical biosensing detection of early cardiac injury enabled by novel self-assembled Bi 2O 3/MgIn 2S 4 photoelectrode coupled with ZnSnO 3 quencher. Talanta 2024; 276:126272. [PMID: 38776780 DOI: 10.1016/j.talanta.2024.126272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/09/2024] [Accepted: 05/15/2024] [Indexed: 05/25/2024]
Abstract
The development of photoelectrochemical (PEC) biosensors plays a critical role in enabling timely intervention and personalized treatment for cardiac injury. Herein, a novel approach is presented for the fabrication of highly sensitive PEC biosensor employing Bi2O3/MgIn2S4 heterojunction for the ultrasensitive detection of heart fatty acid binding protein (H-FABP). The Bi2O3/MgIn2S4 heterojunction, synthesized through in-situ growth of MgIn2S4 on Bi2O3 nanoplates, offers superior attributes including a larger specific surface area and more homogeneous distribution, leading to enhanced sensing sensitivity. The well-matched valence and conduction bands of Bi2O3 and MgIn2S4 effectively suppress the recombination of photogenerated carriers and facilitate electron transfer, resulting in a significantly improved photocurrent signal response. And the presence of the secondary antibody marker (ZnSnO3) introduces steric hindrance that hinders electron transfer between ascorbic acid and the photoelectrode, leading to a reduction in photocurrent signal. Additionally, the competition between the ZnSnO3 marker and the Bi2O3/MgIn2S4 heterojunction material for the excitation light source further diminishes the photocurrent signal response. After rigorous repeatability and selectivity tests, the PEC biosensor exhibited excellent performance, and the linear detection range of the biosensor was determined to be 0.05 pg/mL to 100 ng/mL with a remarkable detection limit of 0.029 pg/mL (S/N = 3).

Anal Bioanal Chem 2024; 416:1961-1970. [PMID: 38349532 DOI: 10.1007/s00216-024-05195-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/28/2024] [Accepted: 02/02/2024] [Indexed: 03/01/2024]
Abstract
Controlling the spread of pathogen requires an efficient and accurate diagnosis. Compared with nucleic acid and antibody detection, antigen assays are more convenient to meet clinical diagnostic needs. However, antigen detection is often difficult to achieve high sensitivity in a limited time. In this work, a novel aptasensing method was designed for the purpose of SARS-CoV-2 antigen detection, using a dumbbell padlock probe-mediated circle-to-circle amplification (C2CA) approach. A sandwich complex of antibody-antigen-aptamer is first formed on the magnetic beads. Afterwards, the signal is amplified by a C2CA reaction involving two tandem rolling circle amplifications. Without special instruments or nanomaterials, a detection limit of 575 fg/mL for S1 protein can be achieved in less than 2 h. In the case of the spike pseudovirus SARS-CoV-2 in artificial saliva, the detection limit is 272 TU/μL, which is much lower than average viral load in patients. Therefore, our method provides a timely, efficient and accurate approach for the clinical diagnosis of SARS-CoV-2. It also opens up the application of C2CA in aptamer sensing and antigen detection.

Abstract
Nanostructures have played a key role in the development of different techniques to attack severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some applications include masks, vaccines, and biosensors. The latter are of great interest for detecting diseases since some of their features allowed us to find specific markers in secretion samples such as saliva, blood, and even tears. Herein, we highlight how hierarchical nanoparticles integrated into two or more low-dimensional materials present outstanding advantages that are attractive for photonic biosensing using their nanoscale functions. The potential of nanohybrids with their superlative mechanical characteristics together with their optical and optoelectronic properties is discussed. The progress in the scientific research focused on using nanoparticles for biosensing a variety of viruses has become a medical milestone in recent years, and has laid the groundwork for future disease treatments. This perspective analyzes the crucial information about the use of hierarchical nanostructures in biosensing for the prevention, treatment, and mitigation of SARS-CoV-2 effects.

Abstract
A sandwich "signal-off" type photoelectrochemical (PEC) immunosensor was fabricated based on a composite heterojunction of tungsten oxide/titanium oxide microspheres (WO3/TiO2) acting as signal amplification platform and carbon microspheres loaded by gold nanoparticles (Cs@Au NPs) utilized as the label for detecting antibody. WO3/TiO2 had excellent photoelectric performance, and the results of Mott-Schottky plots, open-circuit voltage, and electron spin resonance spectroscopy indicated that it belonged to the Z-scheme heterojunction transfer mechanism of photogenerated carriers. To achieve the sensitization of PEC immunosensor, Cs@Au NP-labeled immunocomplex can effectively reduce the photocurrent signal. The PEC immunosensors were fabricated under the optimal conditions of 1:1 WO3/TiO2 (molar ratio), 2.0 mg mL-1 WO3/TiO2, and 1.5 mg mL-1 Cs@Au NPs. Through comparison of the detection results of label-free and sandwich-type PEC immunosensors for nucleocapsid (N) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we found that the sensitivity of the sandwich type was 2.53 times the label-free type, and the limit of detection was 0.006 ng mL-1, i.e., 3.17 times lower than the label-free type. This demonstrates that the developed sandwich-type PEC immunosensor will have a brighter application prospect.
