“…A linear calibration plot of y = 0.6456 + 0.0180*log10(x), with R 2 = 0.9681 was obtained. A direct comparison of the sensor developed herein with those reported in the literature is provided in SI Table 2 and Table 3, as can be seen the senor performance in detection limit is better than previously reported SERS platforms 12,14,19,[21][22][23]26 and better than high-end laboratory based HPLC-MS instrumentation or other platforms [43][44][48][49][50][51][52][53][54][55][56][57] .…”

Surface Enhanced Raman is a promising analytical method for harmful pesticides detection. Herein, we demonstrate a rapid method to directly monitor 2,4-D pesticide in water without the need of sample pre-treatment by using Silver-Gum Arabic (Ag-GA) electrochemically co-deposited SERS substrates. The facile electrochemical synthesis of the large-area (40 µm x 20 µm) SERS substrates needs only 10 seconds, with 2 μL AgNO3 and Gum Arabic mixed solution. Different mor-phologies including Ag-GA spherical nanoparticles and nano dendrites were synthesized by tuning the deposition parame-ters. This study therefore offers a novel way to fabricate SERS substrates for rapid determination of 2,4-D pesticides down to 1 pM in deionized water and 0.15 nM in commercial bottled and also river water samples

“…In electrochemical DNA biosensing, after the target DNA is hybridized with the immobilized capture probe, the target DNA can be quantitatively analyzed by detecting the signal intensity or change value of the quantitatively labeled electroactive probe. For example, ferrocene (Fc), methylene blue (MB), and so on [53,54] have been widely used as electroactive probes for electrochemical biosensing analysis of DNA due to their excellent redox properties. In order to introduce Fc and other electroactive probes into the electrochemical sensor analysis platform, the main method is to use hairpin DNA, [55,56] singlestranded DNA [57] modified with electroactive probes such as Fc, or directly label Fc and other electroactive probes to the target DNA by synthesis.…”

The early diagnosis of major diseases, such as malignant tumors, has always been an important field of research. Through screening, early detection of such diseases, and timely and effective treatment can significantly improve the survival rate of patients and reduce medical costs. Therefore, the development of a simple detection method with high sensitivity and strong specificity, and that is low cost is of great significance for the diagnosis and prognosis of the disease. Electrochemical DNA biosensing analysis is a technology based on Watson Crick base complementary pairing, which uses the capture probe of a known sequence to specifically recognize the target DNA and detect its concentration. Because of its advantages of low cost, simple operation, portability, and easy miniaturization, it has been widely researched and has become a cutting-edge topic in the field of biochemical analysis and precision medicine. However, the existing methods for electrochemical DNA biosensing analysis have some shortcomings, such as poor stability and specificity of capture probes, insufficient detection sensitivity, and long detection cycles. In this review, we focus on improving the sensitivity and practicability of electrochemical DNA biosensing analysis methods and summarize a series of research work carried out by using electrically neutral peptide nucleic acid as an immobilized capture probe.
