Abstract
Real-time polymerase chain reaction (PCR) technology is essential in nucleic acid detection and point-of-care testing (POCT). However, nowadays, the classical qPCR instrument has the deficiency of its bulky volume, high cost, and inconvenience to use; hence, a low-cost and easy-to-use PCR equipment was thus developed consisting of a hardware subsystem as well as a software subsystem based on an improved proportional-integral-derivative (PID) system. The proposed system not only could hold self-setting reaction cycles of temperature rising and falling automatically but also the temperature during the constant temperature stage was regulated steady based on improved temperature control algorithm, which proved its great effect compared with the reaction temperature derived from an infrared thermal imaging camera. The experimental results in gene detection research also could indicate its applicability and stability of our developed PCR system by using the amplification curve analysis, the melting curve analysis, and agarose gel electrophoresis analysis compared with the commercial PCR instrument, which illustrates the great potential application value of the proposed PCR system.

Abstract
Polymerase chain reaction (PCR) is an extremely important tool for molecular diagnosis, as it can specifically amplify nucleic acid templates for sensitive detection. As another division of PCR, free convective PCR was invented in 2001, which can be performed in a capillary tube pseudo-isothermally within a significantly short time. Convective PCR thermal cycling is implemented by inducing thermal convection inside the capillary tube, which stratifies the reaction into spatially separate and stable melting, annealing, and extension zones created by the temperature gradient. Convective PCR is a promising tool that can be used for nucleic acid diagnosis as a point-of-care test (POCT) due to the significantly simplified heating strategy, reduced cost, and shortened detection time without sacrificing sensitivity and accuracy. Here, we review the history of free convective PCR from its invention to development and its commercial applications.

Abstract
A novel continuous-flow polymerase chain reaction (PCR) chip has been analyzed in our work. Two temperature zones are controlled by two external controllers and the other temperature zone at the chip center is controlled by the flow rate of the fluid inside a channel under the glass chip. By employing a water cooling channel at the chip center, the sequence of denaturation, annealing, and extension can be created due to the forced convection effect. The required annealing temperature of PCR less than 313 K can also be demonstrated in this chip. The Poly(methyl methacrylate) (PMMA) cooling channel with the thin aluminum cover is utilized to enhance the temperature uniformity. The size of this chip is 76 mm × 26 mm × 3 mm. This device represents the first demonstration of water cooling thermocycling within continuous-flow PCR microfluidics. The commercial software CFD-ACE+(TM) is utilized to determine the distances between the heating assemblies within the chip. We investigate the influences of various chip materials, operational parameters of the cooling channel and geometric parameters of the chip on the temperature uniformity on the chip surface. Concerning the temperature uniformity of the working zones and the lowest temperature at the annealing zone, the air gap spacing of 1 mm and the cooling channel thicknesses of 1 mm of the PMMA channel with an aluminum cover are recommended in our design. The hydrophobic surface of the PDMS channel was modified by filling it with 20 % Tween 20 solution and then adding bovine serum albumin (BSA) solution to the PCR mixture. DNA fragments with different lengths (372 bp and 478 bp) are successfully amplified with the device.

Abstract
In the field of continuous-flow PCR, the amplification throughput in a single reaction solution is low and the single-plex PCR is often used. In this work, we reported a flow-based multiplex PCR microfluidic system capable of performing high-throughput and fast DNA amplification for detection of foodborne bacterial pathogens. As a demonstration, the mixture of DNA targets associated with three different foodborne pathogens was included in a single PCR solution. Then, the solution flowed through microchannels incorporated onto three temperature zones in an oscillatory manner. The effect factors of this oscillatory-flow multiplex PCR thermocycling have been demonstrated, including effects of polymerase concentration, cycling times, number of cycles, and DNA template concentration. The experimental results have shown that the oscillatory-flow multiplex PCR, with a volume of only 5 μl, could be completed in about 13 min after 35 cycles (25 cycles) at 100 μl/min (70 μl/min), which is about one-sixth of the time required on the conventional machine (70 min). By using the presently designed DNA sample model, the minimum target concentration that could be detected at 30 μl/min was 9.8 × 10(-2) ng/μl (278-bp, S. enterica), 11.2 × 10(-2) ng/μl (168-bp, E. coli O157: H7), and 2.88 × 10(-2) ng/μl (106-bp, L. monocytogenes), which corresponds to approximately 3.72 × 10(4) copies/μl, 3.58 × 10(4) copies/μl, and 1.79 × 10(4) copies/μl, respectively. This level of speed and sensitivity is comparable to that achievable in most other continuous-flow PCR systems. In addition, the four individual channels were used to achieve multi-target PCR analysis of three different DNA samples from different food sources in parallel, thereby achieving another level of multiplexing.

Abstract
In this article we present a long target droplet polymerase chain reaction (PCR) microsystem for the amplification of the 16S ribosomal RNA gene. It is used for detecting Gram-positive and Gram-negative pathogens at high-throughput and is optimised for downstream species identification. The miniaturised device consists of three heating plates for denaturation, annealing and extension arranged to form a triangular prism. Around this prism a fluoropolymeric tubing is coiled, which represents the reactor. The source DNA was thermally isolated from bacterial cells without any purification, which proved the robustness of the system. Long target sequences up to 1.3 kbp from Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa have successfully been amplified, which is crucial for the successive species classification with DNA microarrays at high accuracy. In addition to the kilobase amplicon, detection limits down to DNA concentrations equivalent to 10(2) bacterial cells per reaction were achieved, which qualifies the microfluidic device for clinical applications. PCR efficiency could be increased up to 2-fold and the total processing time was accelerated 3-fold in comparison to a conventional thermocycler. Besides this speed-up, the device operates in continuous mode with consecutive droplets, offering a maximal throughput of 80 samples per hour in a single reactor. Therefore we have overcome the trade-off between target length, sensitivity and throughput, existing in present literature. This qualifies the device for the application in species identification by PCR and microarray technology with high sample numbers. Moreover early diagnosis of infectious diseases can be implemented, allowing immediate species specific antibiotic treatment. Finally this can improve patient convalescence significantly.
