  • Detection of Tilted Fiber Bragg Grating Fiber-Optic Sensors with Short-Term KLT: Towards Low-Cost Biosensors

    Tilted Fiber Bragg Grating (TFBG) optical fiber sensors can be employed as refractive index sensors, and functionalized as biosensors. The TFBG cladding modes exhibit a small yet detectable sensitivity to the refractive index in the surrounding of the sensing region. One of the weaknesses of TFBG is that classical interrogation methods require narrow wavelength resolution to analyze these spectral features which can be achieved only through a bulky setup. In this work, we propose a demodulation method, namely the short term Karhunen-Loeve Transform (ST-KLT) that can be applied to a low-cost spectrometer that detects the TFBG reflection spectrum. The method is capable of detecting refractive index variations in the order of 10-3 - 10-4 refractive index units (RIU), and is this a potential pillar towards low-cost TFBG biosensors.

  • Low cost and high specific anesthetic biosensors with functionally imprinted nanocavities on polymer films

    This paper presents low cost and high specific anesthetic biosensors with functionally imprinted nanocavities on polymer films. Propofol (2, 6-di- isopropylphenol) is an intravenous anesthetic, widely used in induction of anesthesia, total intravenous anesthesia and sedation of intensive care unit patients. Although the propofol concentration in blood can be detected by high-performance liquid chromatography and/or gas chromatography, these methods are time-consuming and not ease of access. In this work, we control the morphology of imprinted nanocavities on molecularly imprinted biosensors by adjusting polymer composition. Our developed biosensors have been compared with a conventional spectrophotometer to investigate surface morphology and performance of the anesthetic biosensors. The performance of the anesthetic biosensors can be enhanced by adjusting morphology of imprinted nanocavities. The newly developed biosensors have been characterized using our developed optofluidic microsystem.

  • Enzymatic Biosensors towards a Multiplexed Electronic Detection System for Early Cancer Diagnostics

    Enzymatic biosensors are expected to play a key-role in bio techno logical and biochemical analysis as shown by the success of glucose sensors in diabetes treatment. The aim of this work is to develop a multiplexed electronic detection system for early cancer diagnostics. Therefore, various enzymes were adsorbed to differently modified surfaces. Electrochemical optical waveguide lightmode spectroscopy (EC-OWLS) and electrochemical quartz crystal microbalance with dissipation (EC-QCM-D) were used to measure the mass and the activity of the adsorbed enzymes. The enzymes were specifically immobilized on a protein resistant PLL-g-PEG surface in order to reduce the loss of activity due to denaturation. In addition, enzymes were also incorporated into DNA- tagged vesicles to increase the signal and therefore the sensor sensitivity. The enzymatic activity of the different systems was compared. To further increase the sensitivity, ferrocyanide was used as an electron mediator.

  • An interrogating circuit and device for magnetostrictive biosensors

    High performance biosensors for the detection of bacterial in various media have been developed using magnetostrictive/magnetoelastic resonators (MSRs). An MSR is a strip of magnetostrictive alloy coated with biological molecular recognition unit, such as antibody and phage. The sensor is based on the change in its resonant frequency. Therefore, it is critical to determine the resonant frequency of an MSR. The MSR biosensors have been developed for the detection of various pathogenic bacteria in liquid food and on the surface of fresh produce in real-time and in-situ manner. However, the instruments used to determine the resonant frequency of these sensors are bulky and expensive. Here an inexpensive circuit is developed to characterize the resonant frequency of the MRS sensors. The unique circuit design makes it is possible to have a real handheld device for the interrogation of MRS sensors. Additionally, a new methodology to enhance the signal is also introduced.

  • Nano-fabrication dependent quality factor in photonic crystal slab biosensors

    Photonic crystal slabs (PCS) are attractive for label-free optical bio-sensors inside micro-fluidic portable diagnostic systems due to their high sensitivity and easy coupling to external radiation. Obtaining high quality factor (Q) values for the guided resonances in these index-of-refraction PCS biosensors is crucial for high sensitivity. Non-ideal fabrication of the hole array in the PCS due to electron beam writing, pattern transfer, and reactive ion etching (RIE) steps will result in imperfect circular hole shapes, and non vertical hole profile that can reduce the Q values. We evaluate the effect of nano-fabrication on the quality factor of guided resonances in PCS biosensors and investigate the potential limitations on sensitivity with current fabrication technologies in a realistic PCS biosensor due to fabrication errors. Spectral broadening of the guided resonances (lower Q values) is found for the fundamental guided resonance modes but no significant changes were observed in higher order guided resonances. These fin dings are consistent with reduced bio-sensing sensitivity in higher order modes due to reduced field overlap with the analyte in side the micro-fluidic channels.

  • Design of surface plasmon resonance biosensors by using powell lens

    Surface plasmon resonance (SPR) biosensors by using Powell lens is proposed. By taking an advantage of Powell lens which distributes light intensity uniformly along the length of line, broad range of samples can be measured without using a motorized rotation stage. This results in simple and compact optoelectronic sensors. A preliminary experimental verification shows that a dip intensity of light reflectance from measurement of the refractive index of air can be obtained by using the proposed sensor.

  • A novel packaging technology for disposable FET-based biosensors with microfluidic channels

    FET devices are extensively used for sensors, including gas sensors and biosensors. In contrast to traditional resistive devices, FET has transconductance gain, which can significantly improve the S/N ratio. Recently, more applications in biosensors combine microfluidic channels and FET system. In FET-based biosensors, the wafer manufacturing process always requires a lot of cost, and it is used for metal lines as interconnects. Miniaturized chip plays a key role in reducing the manufacturing cost. However, simultaneously integrating the sensor and microfluidic channels on one chip is challenging. In this study, a novel and robust packaging method has been developed, to effectively reduce the size of the sensor chip and thereby the cost. 1 mm × 1mm FET sensor chip has been fabricated and embedded in epoxy. Photolithography and metal deposition were done followed by lift-off process for metal interconnect. The FET-embedded chip was passivated and covered by the microfluidic channel made of PMMA.

  • Designing Real-Time Biosensors and Chemical Sensors Based on Defective 1-D Photonic Crystals

    In this letter, we have designed a new biosensing and chemical sensing structure based on 1-D photonic crystals. The proposed structure is a 1-D photonic crystal with a gradient refractive index (GRIN) defect layer in the middle of the structure and two microfluidic channels around the central defect layer. As a result of the introduced GRIN defect layer, which has a spatial refractive index distribution function, spatial defect modes will appear in the first bandgap. By irradiating a beam of light in a chosen frequency of defect modes to the structure, a ring-shaped intensity distribution appears on the output plane of the structure. The radius of this ring is highly sensitive to the refractive index of the fluid that is in two microfluidic channels. By variation of the refractive index, the radius of the ring-shaped intensity profile will change that can be detected by scanning slit beam profilers. The refractive index resolution of Δn = 0.0001 RIU that causes 3.6 μm change in the radius of the ring-shaped intensity can be detected by the introduced structure. One of the key advantages of the proposed sensor is the possibility of real-time monitoring of the variation of refractive indices due to its fast reply to the refractive index changes. As an important example in medical sciences, aggregation of some proteins can cause the variation of the effective refractive index of the solution, which can be monitored in real time by the highly sensitive designed sensor.

  • Design of a Potentiostat with Standalone Signal Generator for Vanillylmandelic Acid Biosensors

    In this paper, a portable potentiostat with standalone signal generator is proposed for the signal processing of vanillylmandelic acid (VMA) biosensors. The proposed potentiostat primarily consists of two microprocessors: one is used to design the programmable waveform generator, and the other is used to measure the current of the biosensors. It can perform general electrochemical analysis functions, such as cyclic voltammetry, linear sweep voltammetry, differential pulse voltammetry, amperometry, and potentiometry. In the experiment, we adopt a VMA biosensor to verify the performance of the proposed potentiostat. The experimental results show that the proposed potentiostat has the merits of good accuracy, low cost, low power consumption, and high portability.
