Polycyclic aromatic hydrocarbons (PAHs) are the widespread environmental contaminants that can be found in atmosphere, water, soil, sediment and organisms. Among most dangerous PAHs is benzo[a]pyrene (BP). The effects of BP on health are: short-term when people are exposed to it at levels above the maximum contaminant level (MCL) (0.2 ppm) for relatively short periods of time leading to red blood cells damage, anemia ect; suppression of immune system and long-term, when human beings are exposured do BP influence at levels above the MCL namely effects on reproducibility and high probability of cancer illnesses. There are known methods for PAHs detection, such as chromatography, immuno-chemistry, biological and chemical ones. However, they have several disadvantages, including high cost, duration and complexity of the analysis procedure, the high detection limit and low selectivity. So at present a development of a new method of PAHs detection based on modern technologies and materials such as nanotechologies and nanomaterials. Belonging to above mentioned is nanophotonic method of PAHs assay. Nanophotonic method for PAHs detection in particular BP in water is a combination of electrochemical and electrochemiluminescence analysis with the application of nanomaterials and nanotechnologies. This method can be carried out using nanophotonic sensor based on nanomaterials such as semiconductor quantum dots (QDs).

Glyphosate (GLY) is a post-emergence and non-selective systematic herbicide which is effective in weed control for annual grasses, broadleaf weeds and perennial weeds. Due to its relatively low toxicity toward environment and organism, it is widely used around the world (including Taiwan). GLY has low volatility and possesses no UV absorption or fluorescence properties, therefore, causing some difficulties in gas or liquid chromatographic analyses. Derivatization is generally necessary before analysis, but derivatization process is always tedious and time consuming.   In this research, an analytical method for GLY in soil based on magnetic solid-phase extraction (SPE) coupled with capillary electrophoresis / Ru(bpy)33+ electrochemiluminescence detection was developed. The soil samples were air-dried, grounded and sifted, followed by extraction with distilled water. The aqueous extract was further extracted by using iron oxide magnetic nanoparticles. The final extract was directly analyzed by CE-ECL method. With spiked GLY in five different soil samples, the linear range was 1 ~ 100 μg/g. The limits of detection were in the range 0.07 ~ 1.83 μg/g, calculated as three times signal-to-noise ratio (S/N=3). The enrichment factor was in the range 15 ~ 50-fold. Under optimum conditions, the total analysis time of soil samples, including pre-treatment, SPE and CE/ECL analysis,was about 30 min. The CE/ECL method can be use for direct analyzing GLY without prior derivatization. The method is rapid, sensitive, convenient and environmental friendly, which can be applied to determine residue GLY in soil.

Based on the linear relationship between concentration of H2O2 and the decrease of electrochemiluminescence (ECL) intensity in a Ru(bpy)32+/TPA system, procedures for the indirect determination of glucose with a flow injection analysis were developed. By passing solutions of glucose through a FIA system containing a glucose oxidase (GOx) immobilized sol-gel column and an ECL system of Ru(bpy)32+ and TPA, glucose can be determined optimally with a detection limit of 1.0 μM in a linear dynamic range of 1.0 – 200.0 μM. A repetitive injection of glucose (100 μM) and human serum solutions gave satisfactory reproducibility with relative standard deviations of 1.3 (N=31) and 3.9 % (N=42) respectively. Interference due to the presence of ascorbic acid, uric acid or other reducible agents in solution can be corrected by passing sample solutions through another sol-gel column that contained no GOx. From the agreement between the contents of glucose in human serum and soft drink analyzed by the developed method and those obtained by the spectroscopy method based glucose assay kit and satisfactory recovery of glucose from interferent containing solutions, the feasibility of the developed method for real sample analysis was confirmed. One of the major purposes of this study was to develop new immobilization approaches and flow cell designs for the fabrication of regenerable ECL-based sensors with improved sensitivity, convenience and long-term stability. Silica particulates were used as immobilization support in ECL sensors for TPA and NAD(P)H and in biosensors for glucose and glucose-6-phosphate(G6P). The first ECL flow cell was fabricated from a glass tube, and a platinum wire was used as working electrode held at +1.3 V. The volume of the flow cell was about 50 μL. An Ag/AgCl electrode and a piece of Pt wire were used as the reference and counter electrode respectively and placed downstream of the working electrode. Ru(bpy)32+ immobilized silica particulates with 1/3 silica sol content showed the best performance for TPA determination, and the sensitivity of TPA determination was dependent upon the amount of Ru(bpy)32+ immobilized in silica particulates. The lowest level of analyte detected for TPA was 0.02μM, and linear range was from 0.02μM to 5μM. Up to a certain concentration level, it was found that Ru(bpy)32+ was tightly held in silica particulates and did not leach out into aqueous solutions, even with continuous flow for up to ten hours. Ru(bpy)32+ immobilized silica particulates were characterized of well activity and high stability; that stored at 0℃ exhibited its original activity for up to one year. The second ECL flow cell was fabricated from a piece of epoxy block supported Pt electrode (1 × 2 cm) as counter electrode, a piece glass window and a polyethylene spacer with 78 μL cell volume, two 2.0-cm length of 0.6-mm diameter platinum wires were used as working electrodes held at +1.1 V, and an Ag/AgCl electrode as reference electrode. All three electrodes were incorporated within the main body of the cell. One of the biosensor design packed Ru(bpy)32+ incorporated silica particulates in the ECL flow cell, and a glucose dehydrogenase (GDH) immobilized silica sol-gel column is placed between the sample injection valve and the flow cell. The ECL response to samples containing glucose and cofactor (NADP) results from the Ru(bpy)33+ ECL reaction with NADPH produced by glucose dehydrogenase. This ECL biosensor was shown applicable for both NAD+- and NADP+- dependent enzymes, where NADH detection ranged from 0.50μM – 5.0 mM NADH and NADPH detection ranged from 1.0μM - 3.0 mM NADPH. Glucose can be determined in a linear dynamic range of 5.0 - 500 μM. Another biosensor design immobilized glucose-6-phosphate dehydrogenase(G6PDH)onto the Ru(bpy)32+ -doped silica particulates through silica chemistry and then packed these particulates into the ECL flow cell. By passing samples containing G6P and cofactor (NAD) through the ECL flow cell, G6P can be determined in a linear dynamic range of 10.0 μM-1.0 mM. The regenerable ECL biosensor was characterized of good reproducibility and well stability for flow injection analysis. A repetitive injection of NADH (100 μM) and G6P(500μM)gave satisfactory reproducibility with relative standard deviations of 2.8 %(N=105)and 2.8 % (N=40) respectively.

In electrochemiluminescence (ECL) studies, Tris (bipyridine)ruthenium(II) chloride (Ru(bpy)3 2+) and its derivatives have been used as primary luminophores since 1972. The flexible solubility in both aqueous and non-aqueous medium and the remarkable intrinsic properties like chemical, optical and desirable electrochemical behavior drives the researcher to use Ru(bpy)3 2+ and its derivatives as highly active ECL probes in modern analytical science. Novel surface modification of Ru(bpy)3 2+ based ECL platforms are highly useful in the selective and sensitive detection of biomolecules, DNA analysis, immunoassays detection, and imaging of the biologically important molecules in cells and tissue of living organisms. This chapter discusses and highlights the most significant works in Ru(bpy)3 2+ based ECL properties of reaction mechanisms and their applications.
