Abstract
Uracil-DNA glycosylase (UDG) is a protein enzyme that initiates the base excision repair pathway for maintaining genome stability. Sensitive detection of UDG activity is important in the study of many biochemical processes and clinical applications. Here, a method for detecting UDG is proposed by integrating magnetic separation and real-time ligation chain reaction (LCR). First, a DNA substrate containing uracil base is designed to be conjugated to the magnetic beads. By introducing a DNA complementary to the DNA substrate, the uracil base is recognized and removed by UDG to form an apurinic/apyrimidinic (AP) site. The DNA substrate is then cut off from the AP site by endonuclease IV, releasing a single-strand DNA (ssDNA). After magnetic separation, the ssDNA is retained in the supernatant and then detected by real-time LCR. The linear range of the method is 5 × 10-4 to 5 U/mL with four orders of magnitude, and the detection limit is 2.7 × 10-4 U/mL. In the assay, ssDNA template obtained through magnetic separation can prevent other DNA from affecting the subsequent LCR amplification reaction, which provides a simple, sensitive, specific, and universal way to detect UDG and other repair enzymes. Furthermore, the real-time LCR enables the amplification reaction and fluorescence detection simultaneously, which simplifies the operation, avoids post-contamination, and widens the dynamic range. Therefore, the integration of magnetic separation and real-time LCR opens a new avenue for the detection of UDG and other DNA repair enzymes.

Abstract
Fusion genes, playing a causal role in human tumorigenesis and developments, are deemed as gold standard molecular biomarkers in cancer diagnosis, therapy, and prognosis. A rapid, robust, and sensitive method of detection of fusion genes for point-of-care (POC) diagnosis is urgently needed. Here, taking the advantages of the superior specificity of the ligation reaction and the highly amplified efficiency of isothermal exponential amplification with a pH indicator, we developed a colorimetric method for visual detection of fusion genes with high sensitivity and specificity by the naked eye. More importantly, we first found that fusion genes can be accurately quantified in a wide dynamic range (2 zmol to 2 fmol) by an open-source app with a smartphone-assisted RGB (red, green, and blue value) reading mode. The proposed method for Visual detection of Fusion genes by Ligation-triggered Isothermal Exponential Amplification is termed Vis-Fusion LIEXA. We have demonstrated that the Vis-Fusion LIEXA is a practical and reliable method for accurate quantitative detection of the fusion gene in a complex biological sample at zmol level in 40 min only with a smartphone, thereby providing a user-friendly and point-of-care testing (POCT) tool for molecular diagnostics.

Abstract
Precise detection of the low copy numbers of messenger RNA (mRNA) mutation in single cells is of great significance but still remains challenging. Herein, by integrating the outstanding features of a rationally designed peptide nucleic acid (PNA) clamp for highly selective discrimination of single-nucleotide variation, and droplet digital PCR for ultrasensitive and precise quantification, we have developed a robust one-step droplet digital reverse transcription PCR (ddRT-PCR) method which enables precise mRNA mutation detection in single cells with ultrahigh specificity to clearly discern as low as 0.01% mutated mRNA in a high background of wild-type mRNA. Because of its outstanding single-molecule level sensitivity and ultrahigh specificity, this ddRT-PCR method holds great promise for studying cellular heterogeneity at the single cell level, as well as for the precise quantification of mutant mRNAs in complex plasma or serum for liquid biopsy.

Abstract
Herein, we present a novel gold nanoparticle (AuNP) enumeration-based colorimetric aptamer biosensor for ultrasensitive detection of nucleic acid. This AuNP enumeration-based colorimetric method takes advantages of the distinctive and strong localized surface plasmon resonance light scattering with the dark-field microscope. In our model system, first, cost-effective DNA1 instead of expensive 2-thioethyl ether acetic acid was capped on the surface of AuNPs to form a dense DNA1 layer. Then, two DNA strands (DNA2 and DNA3) in two different solutions were separately asymmetrically functionalized on the AuNPs capped dense DNA1 layer. The subsequent binding of the target DNA could trigger the formation of perfect complementary DNA with a Y shape and adjust the distance between nanoparticles to form AuNP dimers, accompanied by a color change from green to yellow as observed, and thereby modulated the performance of the sensor, which resulted in the ultrahigh sensitivity. With this design, a 43 aM limit of detection was obtained, which exhibited an increase of at least 5-9 orders of magnitude in sensitivity over other colorimetric sensors fabricated using conventional strategies.
