“…The overlap of the excitation wavelength of the Raman laser with the resonance wavelength of the plasmon structure has made it possible to use SERS spectroscopy in sensors and various laboratory analyses. This is because the resonance of the substituted surface plasmons plays an important role in electromagnetic amplification [ 35 , 36 ]. Therefore, the preparation of colloids and metal substrates with the ability to generate and maintain plasmonic effects is of great interest [ 37 , 38 ].…”

COVID-19 continues to spread and has been declared a global emergency. Individuals with current or past infection should be identified as soon as possible to prevent the spread of disease. Surface-enhanced Raman spectroscopy (SERS) is an analytical technique that has the potential to be used to detect viruses at the site of therapy. In this context, SERS is an exciting technique because it provides a fingerprint for any material. It has been used with many COVID-19 virus subtypes, including Deltacron and Omicron, a novel coronavirus. Moreover, flexible SERS substrates, due to their unique advantages of sensitivity and flexibility, have recently attracted growing research interest in real-world applications such as medicine. Reviewing the latest flexible SERS-substrate developments is crucial for the further development of quality detection platforms. This article discusses the ultra-responsive detection methods used by flexible SERS substrate. Multiplex assays that combine ultra-responsive detection methods with their unique biomarkers and/or biomarkers for secondary diseases triggered by the development of infection are critical, according to this study. In addition, we discuss how flexible SERS-substrate-based ultrasensitive detection methods could transform disease diagnosis, control, and surveillance in the future. This study is believed to help researchers design and manufacture flexible SERS substrates with higher performance and lower cost, and ultimately better understand practical applications.

“…1 With the rapid development of nuclear weapons and the nuclear industry under the public spotlight, public concerns about uranium mining and environmental management have become increasingly pressing. [2][3][4] Any link from uranium mining to the disposal of the radioactive wastewater may result in the unavoidable release of uranium into the environment, 5,6 which is susceptible to flow across regions with the change in the water environment surrounding uranium mines, 7 leading to the distribution of uranium in soil and water. 8,9 Uranyl ions (UO 2 2+ ) are the most stable and prevalent form of uranium that can be found in the environment.…”

“…UO 2 2+ -specific DNAzyme was firstly selected by Lu group and a fluorescent sensor was developed simultaneously ( Liu et al, 2007 ). In the past few years, quite a few amplified sensing platforms had been established for the quantitative detection of UO 2 2+ ( Farzin et al, 2019 ; He and Hua, 2019 ; Wu et al, 2019 ; Wang et al, 2022 ). In this review, we only focused on the application of various types of DNAzymes-based methods with diverse signals outputting approaches to achieve quantitative detection of uranyl ion.…”

Nuclear facilities are widely used in fields such as national defense, industry, scientific research, and medicine, which play a huge role in military and civilian use. However, in the process of widespread application of nuclear technology, uranium and its compounds with high carcinogenic and biologically toxic cause a lot of environmental problems, such as pollutions of water, atmosphere, soil, or ecosystem. Bioensors with sensitivity and specificity for the detection of uranium are highly demand. Nucleic acid enzymes (DNAzyme) with merits of high sensitivity and selectivity for targets as excellent molecular recognition elements are commonly used for uranium sensor development. In this perspective review, we summarize DNAzyme-based biosensors for the quantitative detection of uranyl ions by integrating with diverse signal outputting strategies, such as fluorescent, colorimetry, surface-enhanced Raman scattering, and electrochemistry. Different design methods, limit of detection, and practical applications are fully discussed. Finally, the challenges, potential solutions, and future prospects of such DNAzyme-based sensors are also presented.
