Abstract
As a burgeoning non-invasive indicator for reproducible cancer diagnosis, tumor-related biomarkers have a wide range of applications in early cancer screening, efficacy monitoring, and prognosis predicting. Accurate and efficient biomarker determination, therefore, is of great importance to prevent cancer progression at an early stage, thus reducing the disease burden on the entire population, and facilitating advanced therapies for cancer. During the last few years, various DNA structure-based fluorescent probes have established a versatile platform for biological measurements, due to their inherent biocompatibility, excellent capacity to recognize nucleic and non-nucleic acid targets, obvious accessibility to synthesis as well as chemical modification, and the ease of interfacing with signal amplification protocols. After decades of research, DNA fluorescent probe technology for detecting tumor-related mRNAs has gradually grown to maturity, especially the advent of fluorescent nanoprobes has taken the process to a new level. Here, a systematic introduction to recent trends and advances focusing on various nanomaterials-related DNA fluorescent probes and the physicochemical properties of various involved nanomaterials (such as AuNP, GO, MnO2, SiO2, AuNR, etc.) are also presented in detail. Further, the strengths and weaknesses of existing probes were described and their progress in the detection of tumor-related mRNAs was illustrated. Also, the salient challenges were discussed later, with a few potential solutions.

A One-Step Electrochemical Aptasensor Based on Signal Amplification of Metallo Nanoenzyme Particles for Vascular Endothelial Growth Factor. Front Bioeng Biotechnol 2022; 10:850412. [PMID: 35615476 PMCID: PMC9124786 DOI: 10.3389/fbioe.2022.850412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Accepted: 03/21/2022] [Indexed: 11/13/2022] Open
Abstract
In this study, a one-step electrochemical aptasensor was developed to detect the biomarker vascular endothelial growth factor (VEGF), an important protein in the pathogenesis of many retinal diseases, including age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity, and retinal vein occlusion. The aptamer has a good affinity and can rapidly identify and capture VEGF based on its unique structure. We designed a VEGF aptasensor based on the aptamer recognition and complex metallo nanoenzyme particles as an electron exchange center and bridge between capture DNA and electrode. The aptamers maintained the hairpin structure to avoid nonspecific surface adsorption and expose the capture sequence outwards when the target was inexistent. Conversely, the aptamers opened the hairpin structure to release space to accomplish binding between VEGF and DNA, resulting in increased impedance. The performance of the electrochemical aptasensor is detected by electrochemical impedance spectroscopy (EIS). The limit of detection by EIS was as low as 8.2 pg ml-1, and the linear range was 10 pg ml-1-1 μg ml-1. The electrochemical aptasensor also showed high specificity and reproducibility.

Abstract
Monitoring the expression level of the intracellular tumor suppressor gene p21 mRNA is essential to reveal the progress and prognosis of a tumor. Methods widely reported for the detection of p21 mRNA are the real-time polymerase chain reaction and Northern blot. However, these methods only detect mRNA in vitro and cannot realize the in situ monitoring of the p21 mRNA expression level in living cells. Additionally, the sensor for the real-time tracking and monitoring of the p21 mRNA location without the help of a transfection reagent in living cells is still limited. Herein, a novel sticky-flare was constructed for the dynamic monitoring of the temporal and spatial variations of p21 mRNA in living cells. The nanoprobe consists of AuNP, a recognition sequence modified with Cy5, and a thiol-modified DNA sequence. The thiol oligonucleotide strand could act partially complementary to the Cy5-modified oligonucleotide strand to form a double-stranded DNA linked to AuNP, resulting in the fluorescence quenching of Cy5 due to the energy transfer from Cy5 to the gold sphere. In the presence of p21 mRNA, the Cy5-modified recognition nucleic acid specifically bound to p21 mRNA to form a more stable double chain and escaped from the gold sphere, leading to the recovery of red fluorescence. Our method is better than other methods in its ability to quantify the spatial distribution and expression level of p21 mRNA in living cells and discriminate various tumor cell lines with different p21 mRNA expression levels by the naked eye. Particularly, the sticky-flare probe used in this assay could allow the visual evaluation of the tumor treatment effect and the determination of the tumor progression stage by enabling monitoring of the relative expression level of p21 mRNA in tumor cells after cisplatin treatment. The method reported here is accurate, reliable and needs no auxiliary tools (transfection reagent), and thereby provides a promising route for the prognostic evaluation and drug development of cancer treatment in the future.

Recent advances of fluorescent biosensors based on cyclic signal amplification technology in biomedical detection. J Nanobiotechnology 2021; 19:403. [PMID: 34863202 PMCID: PMC8645109 DOI: 10.1186/s12951-021-01149-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Accepted: 11/17/2021] [Indexed: 12/18/2022] Open
Abstract
The cyclic signal amplification technology has been widely applied for the ultrasensitive detection of many important biomolecules, such as nucleic acids, proteins, enzymes, adenosine triphosphate (ATP), metal ions, exosome, etc. Due to their low content in the complex biological samples, traditional detection methods are insufficient to satisfy the requirements for monitoring those biomolecules. Therefore, effective and sensitive biosensors based on cyclic signal amplification technology are of great significance for the quick and simple diagnosis and treatment of diseases. Fluorescent biosensor based on cyclic signal amplification technology has become a research hotspot due to its simple operation, low cost, short time, high sensitivity and high specificity. This paper introduces several cyclic amplification methods, such as rolling circle amplification (RCA), strand displacement reactions (SDR) and enzyme-assisted amplification (EAA), and summarizes the research progress of using this technology in the detection of different biomolecules in recent years, in order to provide help for the research of more efficient and sensitive detection methods.
