Enzymatic luminescent systems are a promising tool for rapid detection of heavy metals ions for water quality assessment. Nevertheless, their widespread use is limited by the lack of test procedure automation and available sensitive handheld luminometers. Herein we describe integration of disposable microfluidic chips for bioluminescent enzyme-inhibition based assay with a handheld luminometer, which detection system is based on a thermally stabilized silicon photomultiplier (SiPM). Microfluidic chips were made of poly(methyl methacrylate) by micro-milling method and sealed using a solvent bonding technique. The composition of the bioluminescent system in microfluidic chip was optimized to achieve higher luminescence intensity and storage time. Results indicate that developed device provided comparable sensitivity with bench-scale PMT-based commercial luminometers. Limit of detection for copper (II) sulfate reached 2.5 mg/L for developed biosensor. Hereby we proved the concept of handheld enzymatic optical biosensors with disposable chips for bioassay. The proposed biosensor can be used as an early warning field-deployable system for rapid detection of heavy metals salts and other toxic chemicals, which affect bioluminescent signal of enzymatic reaction.

Diagnostic Investigation

A lateral flow (LF) device combined with quantum dots (QDs) technology was developed for rapid detection of a specific mycobacterial flavoprotein reductase (<em>fprA</em>). In order to develop the LF assay based on a double-antibody sandwich format, two monoclonal antibodies recognizing different epitopes located in separated <em>fprA</em> domains were identified. The first monoclonal antibody was immobilized onto the detection zone of a porous nitrocellulose membrane, whereas another monoclonal antibody was conjugated to QDs nanoparticles as a detection system. Using these monoclonal antibodies we recorded a good fluorescence signal, the intensity of which was directly proportional to the concentration of <em>fprA</em> protein. The use of antibodies conjugated with fluorescent semiconductor QDs via biotin-streptavidin bridge, allowed the detection of <em>fprA</em> protein at concentrations as low as 12.5 pg/μL in less than 10 min. The reported technology could be useful in the diagnostic investigation of <em>Mycobacterium tuberculosis</em> and other human pathogens in clinical specimens.

Ship Ballast Water

Ship ballast water has been identified as one of four major environmental threats by the international maritime organization. This paper presents a portable on-site rapid detection system of microalgae in ship ballast water. The system consists of a microfluidic chip platform, LED light source and drive systems, optical detection system, ARM software and hardware system, power supply system and so on. Microalgae particles can go through the detection area inside the micro channels one by one by using a sheath fluid focus. The resulting chlorophyll fluorescence is converted to the electrical pulse signal by photodiode. The experimental results show that the system can quickly and accurately detect the ballast water living microalgae concentration. The minimum detectable microalgae size is about 3μm (mean diameter). This system has some advantages such as miniaturized, portable, fast, accurate and label free, and has great potential for on-site rapid detection of ship ballast water.
