Abstract
PCR amplification technology is the cornerstone of molecular biology. All-in-One PCR tube, as an emerging integrated device, is booming in biosensors application. All-in-One PCR tube biosensors are integrated PCR tubes designed for signal recognition, signal amplification or signal output. They enable "one-pot" detection within functionally modified and intelligently fabricated PCR tubes, effectively overcoming the limitations of conventional PCR applications, like complex procedural steps, risk of contamination and so on. Based on this, the review article summarizes the recent advance of All-in-One PCR tube biosensors for the first time as well as systematically categorizes five approaches of functional modification, three types of intelligent fabrication and relevant property characterization techniques. More emphasis is placed on the review of five ways of functional modification, including physical modification, chemical modification, UV photografting surface treatment, plasma surface modification, and layer-by-layer assembly coating. Moreover, All-in-One PCR tube biosensors covering different recognition elements range from small molecules to protein are detailed discussed on principle of sensing, providing a deeper understanding of the design and application of All-in-One-tube biosensor. Last, the future opportunities and challenges in this fascinating field are also deliberated.

Magnetic nanospheres for convenient and efficient capture and release of hepatitis B virus DNA. Talanta 2019; 197:605-611. [PMID: 30771983 DOI: 10.1016/j.talanta.2019.01.077] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Revised: 01/20/2019] [Accepted: 01/24/2019] [Indexed: 11/21/2022]
Abstract
Nucleic acid isolation and purification are essential steps in molecular biology. Currently-used isolation methods focus on the extraction of all the nucleic acids from crude samples, yet ignore the specific nucleic acids of interest, which may induce the loss of the specific nucleic acids and hinder their analyses. Herein, a magnetic nanospheres (MNs)-based strategy for efficient capture and release of specific nucleic acids is developed. The DNA sequence of hepatitis B virus (HBV) is taken as a model to validate this method. The MNs are modified with the complementary strand of HBV DNA for specific capture based on hybridization reaction. Then, by melting at high temperature, the captured DNAs are detached from the MNs to achieve release. The capture and release process are performed conveniently with magnetic separation. High capture efficiency (over 80%) and nearly 100% release efficiency for HBV DNA are achieved respectively via 40 min and 5 min interaction. While non-target DNAs are hardly captured, indicative of good selectivity. Moreover, after releasing DNAs, the MNs are directly regenerated and can be reused without degrading performance, which greatly reduces the operation costs. Finally, this method is applied to serum samples without any pretreatment, which exhibits similar capture and release capacity with those in the ideal samples, indicating its great application potential in practice.

Abstract
The requirement to monitor the presence of genetically modified organisms (GMO) in a variety of marked products has generated an increasing demand for reliable, rapid, and time and cost-effective analytical methods. Here we report an on-site method for rapid detection of cauliflower mosaic virus promoter (CaMV 35S), a common element present in most GMO, using cross-priming amplification (CPA) technology. Detection was achieved using a DNA-based contamination-proof strip biosensor. The limit of detection was 30 copies for the pBI121 plasmid containing the CaMV 35S gene. The certified reference sample of GM maize line MON810 was detectable even at the low relative mass concentration of 0.05%. The developed CPA method had high specificity for the CaMV 35S gene, as compared with other GM lines not containing this gene and non-GM products. The method was further validated using nine real-world samples, and the results were confirmed by real-time PCR analysis. Because of its simplicity, rapidity, and high sensitivity, this method of detecting the CaMV 35S gene has great commercial prospects for rapid GMO screening of high-consumption food and agriculture products.
