“…In comparison with traditional detection methods, like X-ray, HPLC, and HPLC-MS, SPR technology can perform kinetics parameters (association and dissociation process) measurement, concentration measurement, and real-time molecule detection. It has been widely used in chemical, biology, agriculture, environment, and food safety [6][7][8][9][10][11][12].…”

Surface plasmon resonance (SPR) is a real-time, label-free, and high-sensitive detection technology. SPR has been widely used in many applications such as biomolecular interaction analysis, environmental monitoring, and medical diagnostics. However, conventional SPR sensor systems usually require expensive equipment and complicated optics. In this paper, we have demonstrated a rapid prototyping of angle-scanning SPR for bioanalytical investigation. Rapid prototyping was attained by utilizing the FDM (fused deposition modeling) based 3D (three-dimensional) printing technology. Two rotating platforms were employed to drive the laser source and photodiode, respectively. A temperature regulation unit was incorporated to maintain the system temperature in order to reduce the temperature effect. The proposed SPR rapid prototyping yielded a refractive index resolution of 6.4×10 −6 RIU (refractive index unit), and the biotin-avidin system validated the kinetics parameters measurement capability. The obtained results indicated that the FDM 3D printing has great potential for developing rapid-prototyping SPR system.

“…Similar compact SPR sensors based on a gold-coated grating coupled system with a much greater number of channels have been developed. [7][8][9] The sensitivity resolutions of these SPR sensors were almost at the same level as the SPR sensor reported by Piliarik et al Dostálek et al reported a method to prepare an array of gratings for an SPR sensor chip with multi-sensing points. 10 In their reports, an interference pattern generated from two coherent lights was used to prepare a master grating; its pattern was replicated to an elastomer stamp.…”

“…In the case of (1), an SPR sensor chip with an Au layer, which was prepared by depositing Au on a substrate with a grating structure, was assembled into a flow cell having multi-channels, and the reflected light was monitored by a 2-dimension CCD or CMOS sensor. [6][7][8][9] For example, Piliarik et al 6 developed a compact SPR sensor based on a gold-coated grating having 4 channels, and reported that its sensitivity resolution was ca. 3 × 10 -7 RIU.…”

Development of a Portable Surface Plasmon Resonance Sensor with Multi-Sensing Points Based on the Linear CCD Sensor

A portable-type surface plasmon resonance (SPR) sensor, composed from a new optical system for multi-sensing, has been developed to apply to environment analysis, clinical diagnosis etc., where many samples are desired to be analyzed at high throughput. The optical system of the sensor consists of a light-emitting diode, a pair of cylindrical lenses, a pair of collimator lenses, a correction lens, a prism, a polarizer and a linear CCD sensor with 2048 pixels. Reflected light from a sensor chip of the width of 6 mm at a certain incident angle was detected by ca. 618 pixels of the linear CCD sensor as an SPR sensor signal. An SPR sensor signal at a specified incident angle is controllable for optimization by adjusting the position of the CCD sensor. A sensor chip having a 30-stripe linear pattern (100 μm width/stripe) was prepared. The spatial resolution as well as the performance of the sensor were evaluated by using sucrose solutions. As a result, the acquisition of SPR sensor signals from 30 sensing points was successfully achieved with a spatial resolution of 100 μm (distance between 2 sensing points). A lower detection limit of ca. 3.2 -5.5 × 10 -5 RIU with a standard deviation of ±4.5% was obtained by averaging the signals from 6 -7 pixels of the CCD sensor per one sensing stripe.

“…The chip of sensor is discovered to flow channel to ease the goal solutions and successive rinsing [103] (Figure 7). Fernández et al [108] decided the antibiotic detection from milk using SPR lab-on-a-chip approach. The detection limit found becomes 1.1-2.1 ng per mL in diluted (five-fold) milk.…”

Escherichia coli (E. coli) O157:H7 was first recognized in 1982 after investigation of two cases of hemorrhagic colitis and hemolytic uremic syndrome. E. coli O157:H7 the shiga toxin producing strain of E. coli are most commonly involved in many outbreaks of human and animal diseases with low infectious dose. Human infections caused by E. coli O157:H7 are due to consumption of undercooked ground beef, raw milk and raw milk products, water, cold sandwiches, vegetables, raw apple cider and person to person contact. Due to low infectious dose and different mode of transmission it is essential to develop more rapid and sensitive methods for detection of shiga toxin producing E. coli. In this review different molecular based detection methods are discussed. PCR speeds up the analysis time and amplify small number of microbes are described along different variations of PCR following DPCR, omitting the tedious step of DNA extraction. Genomic techniques are reviewed along further epidemiological typing like phage typing and biotyping. Biosensors provide real time detection described along with use of fluorescence and microscopy. Emerging technologies including microarray, molecular beacons and lab-on-a-chip are described along with new improvements in molecular beacons. Merits and demerits of each approach discussed are examined throughout the article.
