Abstract
The continuous progress of society and the vigorous development of science and technology have brought people the dawn of maintaining health and preventing and controlling diseases. At the same time, with the update and iteration of bioinformatics technology, the current biological gene research has also undergone revolutionary changes. However, a long-standing problem in genetic research has always plagued researchers, that is, how to find the most needed sample genes from a large number of sample genes, so as to reduce unnecessary research and reduce research costs. By studying the extraction path of biological genes, it can help researchers to extract the most valuable research genes and avoid wasting time and energy. In order to solve the above problems, this paper used the Bhattacharyya distance index and the Gini index to screen the sample genes when extracting the characteristic genes of breast cancer. In the selected 49 public genes, 6 principal components were extracted by principal component analysis (PCA), and finally the experimental results were tested. It was found that when the optimal number of characteristic genes was selected as 5, the recognition rate of genes reached the highest 90.31%, which met the experimental requirements. In addition, the experiment also proved that the characteristic gene extraction method designed in this paper had a removal rate of 99.75% of redundant genes, which can greatly reduce the time and money cost of research.

Abstract
The ligase chain reaction (LCR), as a classic nucleic acid amplification technique, is popular in the detection of DNA and RNA due to its simplicity, powerfulness, and high specificity. However, homogeneous and ultrasensitive LCR detection is still quite challenging. Herein, we integrate the LCR with a CRISPR-Cas12a system to greatly promote the application of the LCR in a homogeneous fashion. By employing microRNA as the model target, we design LCR probes with specific protospacer adjacent motif sequences and the guide RNA. Then, the LCR is initiated by target microRNA, and the LCR products specifically bind to the guide RNA to activate the Cas12a system, triggering secondary signal amplification to achieve ultrasensitive detection of microRNA without separation steps. Moreover, by virtue of a cationic conjugated polymer, microRNA can not only be visually detected by naked eyes but also be accurately quantified based on RGB ratio analysis of images with no need of sophisticated instruments. The method can quantify microRNA up to 4 orders of magnitude, and the determination limit is 0.4 aM, which is better than those of other reported studies using CRISPR-Cas12a and can be compared with that of the reverse-transcription polymerase chain reaction. This study demonstrates that the CRISPR-Cas12a system can greatly expand the application of the LCR for the homogeneous, ultrasensitive, and visual detection of microRNA, showing great potential in efficient nucleic acid detection and in vitro diagnosis.

Abstract
A method for the ABO and Rhesus (Rh) blood group typing from individual erythrocytes is proposed in this study. Blood-group-specific antibodies immobilized to gold nanoparticles (BG-AuNP) were utilized for the identification of blood groups from individual erythrocytes by objective-type dark-field microscopy (OTDFM). The scattering of free BG-AuNP and their Brownian motion as well as BG-AuNP attached on erythrocytes is easily observed by OTDFM. The strong scattering intensity caused by BG-AuNP packing-enhanced nanoscattering (PENS) on erythrocytes is first demonstrated. PENS combined with OTDFM allows us to identify blood groups within 5 s for all blood group antigens including A, B, D, C, c, E, and e. This was immediately identified by mixing with BG-AuNP without any washing step or waiting for hemoagglutination. Therefore, PENS combined with OTDFM demonstrates feasibility and advantages for use in emergency transfusions where the blood group of patients is unknown. Moreover, matching RhD+ in the case of emergency transfusions may also be beneficial in reducing the shortage of RhD- red blood cell concentrate in the case of a population with a high frequency in RhD-.

Abstract
In situ analysis of tumor-related messenger RNAs (mRNAs) is significant in identifying cancer cells at the genetic level in the early stage. Rolling circle amplification (RCA)-based methods are primary tools for in situ mRNA assay, however, the necessary ligation reaction not only shows low ligation efficiency, but also greatly prolongs the assay time that increases the risk of cells losing and mRNAs leakage. In this work, we propose a novel toehold-mediated ligation-free RCA (TMLFRCA) on a designed structure-switchable dumbbell-shaped probe (SDP). Target mRNA can specifically activate SDP from its circular form by toehold strand displacement, thereby initiates in situ RCA for mRNA imaging with the help of a short DNA primer. For the proof-of-concept demonstration, the TK1 mRNA was sensitively detected by TMLFRCA in less than 3.5 h with a limit of detection (LOD) of 0.39 fM (corresponds to 2.39×108copiesL-1), and significantly improved specificity capable for distinguishing single base difference. The sensitivity of the TMLFRCA for TK1 mRNA in situ assay is ∼29-fold and ∼7-fold higher than that of FISH and ligase-assisted RCA method, respectively, which enables the TMLFRCA method capability of highly sensitive and specific distinction mRNA expression levels between cancer cells and normal cells. We believe this TMLFRCA strategy would be of great value in both basic research and clinical diagnosis.

Abstract
Accurate quantifications of cellular miRNAs are important not only for accelerating them becoming reliable diagnostics biomarkers but also for deeply understanding their influence on central signaling pathways. Although single-molecule miRNA imaging permits quantifying biomolecules at the single-molecule level, it is limited by the sensitivity and specificity of hybridization-based probes. We report a miRNA single-molecule imaging method by using conjugated polymer nanoparticle (CPN) labeled short DNA probe termed as a nanoflare. The transient hybridization of the nanoflares and target miRNAs yields a featured single-molecule kinetics signal rendering high single-molecule sensitivity and specificity. miRNA can be detected with a remarkable detection limit of 1 fM without using any amplification steps. The discrimination capability of homologous miRNAs was also demonstrated. Taking advantage of the featured single-molecule signal of the nanoflare, we can directly count single miR-21 molecules in single cells by using highly inclined and laminated optical sheet (HILO) microscopy. The statistics of the counting reveals miR-21's cell-to-cell fluctuation and differential expression of tumor cells and normal cells.

Abstract
Currently, reported affinity pairings still lack in diversity, and thus terminal protection relying on steric hindrance is restricted in designing nucleic acid-based analytical systems. In this work, resistance to exonuclease is testified by group modification or backbone replacement, and the 3'-phosphate group (P) reveals the strongest exonuclease I-resistant capability. Due to the substrate specificity of enzymatic catalysis, this 3'-P protection works in a "direct mode". By introducing DNA templated copper nanoparticles, an alkaline phosphatase assay is performed to confirm the 3'-P protection. To display the application of this novel terminal protection, a multifunctional DNA is designed to quantify the model circulating microRNA (hsa-miR-21-5p) in serums from different cancer patients. According to our data, hsa-miR-21-5p-correlated cancers can be evidently distinguished from non-correlated cancers. Meanwhile, the effect of chemotherapy and radiotherapy on breast cancer is evaluated from the perspective of hsa-miR-21-5p residue in serums. Since greatly reducing the limitations of DNA design, this P-induced terminal protection can be facilely integrated with other DNA manipulations, thereby constructing more advanced biosensors with improved analytical performances for clinical applications.

Abstract
Although various methods have been developed to suffice the oligonucleotide demand of molecular biology laboratories, in vitro production of high-purity ssDNAs remains to be a challenging task. We hypothesized that complementing the asymmetric PCR with 3' phosphate blocked limiting primer decreases the mispriming thus reduces polymerisation of DNA by-products. The presented results attest our assumption that the primer blocked asymmetric PCR (PBA-PCR) selectively produces ssDNA of interest and is even suitable for effective amplification of DNA libraries of large sequence space. The high-throughput sequence analysis demonstrated that PBA-PCR also alleviates the PCR bias obstacle since it does not distort the sequence space. The practicability of the novel method was verified by monitoring the process of SELEX and screening of aptamer candidates using PBA-PCR produced ssDNAs in Amplified Luminescent Proximity Homogeneous Assay. In summary, we have developed a generally applicable method for straightforward, cost-effective production of ssDNA with on demand labelling.

Abstract
Here we present the realization of a novel fluorescence detection method based on the electromigration of fluorescent molecules within a nanocapillary combined with the laser excitation through a platinum (Pt)-coated nanocapillary. By using the Pt nanocapillary assisted focusing of a laser beam, we completely remove the background scattering on the tip of the electrophoretic nanocapillary. In this excitation geometry, we demonstrate a 1000-fold sensitivity enhancement (1.0 nM to 1.0 pM) compared to the detection in microcapillaries with epifluorescence illumination and fluorescence spectrophotometry. Due to a significant electroosmotic flow, we observe a decelerating migration of DNA molecules close to the tip of the electrophoretic nanocapillary. The reduced DNA translocation velocity causes a two-step stacking process of molecules in the tip of the nanocapillary and can be used as a way to locally concentrate molecules. The sensitivity of our method is further improved by a continuous electrokinetic injection of DNA molecules followed by sample zone stacking on the tip of the nanocapillary. Concentrations ranging from 0.1 pM to 1.0 fM can be directly observed on the orifice of the electrophoretic nanocapillary. This is a 1000-fold improvement compared to traditional capillary electrophoresis with laser-induced fluorescence.

Abstract
The development of non-invasive techniques for the diagnosis of cancer, characterization of mutation and monitoring treatment response could greatly reduce the morbidity and mortality caused by cancer. Nevertheless, the extremely low amount of cell free nucleic acids makes liquid biopsy a very challenging task. Herein, taking advantage of the pocket size, reliable quantitative results and simple operation of the pocket-sized personal glucose meter (PGM), we report an approach of circulating microRNA-21 (miR-21) detection with high precision and low cost. Via target-induced release of invertase from the DNA-invertase conjugate, which could convert sucrose into glucose, the detection of miR-21 in serum was linked to PGM readings. Combining the DNAzyme feedback amplification (DFA) program and highly efficient enzymatic turnover, an ultralow detection limit of 7 × 10-16 M for miR-21 was achieved using a PGM as the reporter. The high sensitivity and selectivity of the proposed method meets the requirement of quantifying cell free nucleic acids in serum. In addition, this approach fills the shortage of quantitative RT-PCR and next-generation sequencing in quantifying miRNAs with a short length and greatly reduces the cost of detection. We believe that widely used personal diagnosis devices could hold an important place in the booming area of liquid biopsy.
