Definitions
- Disposable biosensor for the detection of antigen / antibody bindings in whole blood for use as an anti-HIV confirmation test with a verbal result on a liquid crystal display.
- This biosensor can also be called an immunoassay and belongs to the field of medical technology.
- the partial antigens are openly accessible, even if immobilized in some form.
- Reaction space which is closed by a PZT ceramic plate (PZ) that generates ultrasound.
- the silicon wafer is 1 ⁇ m thick
- LB light guide tracks made of GaAs are attached using the methods of epitaxy and photolithography. They have a diameter of only 2 ⁇ m and guide the parallel polarized light (single mode polarization fibers) in strands of 5 each.
- Infrared light (1150 nm) is led from an LED diode (LD) via a prism arrangement (B) into the light guide (LB).
- a polaroid filter (C) on the surface of the prism that linearly polarizes the light.
- Polarized light is guided in the gallium arsenide conductor tracks (LB) to the individual reflex arrangements (F). There the light falls on the aluminum mirror (Y) at a certain angle for total reflection in the silicon crystal, where it
- the reaction chamber (R) has 3 supply lines, 2 from the blood sampler and one on the opposite side of the reaction chamber from the disinfection device (Fig.7).
- This channel also has an air hole in the disinfection device, so that air in the
- Teflon capillary (T) Reaction space through which the Teflon capillary (T) can be removed and therefore no air bubbles can form. Blood, on the other hand, is repelled by the Teflon (not hydrophilic).
- the reflex arrangement Si chip with diode and prism
- the reflex arrangement is designed in such a way that when the entire Si chip is bent by a force in the middle, the angle of reflection decreases, but when it is pulled it increases.
- the gap (F) ensures that the reflection condition is maintained in the event of deformation.
- Total reflection i.e. minimum intensity at the reference diode, is retained, which is achieved by heating with a resistor that is exactly the same
- the entire Si chip is not initially at rest, as shown in the drawing. but arched upwards by 1 mm.
- the bimetal is heated, the chip goes through the rest position shown in the figure and is now bent downwards. With in-situ adjustment, this process continues until a minimum of light intensity is found on the reference diode. Then the current to the heating resistor is interrupted. Only when the intensity increases to a certain threshold value, the current is switched on again until the relative minimum is reached again.
- the ultrasonic vibration has a frequency of 65 kHz and is generated by an IC from a digital clock and connected to the PZT plate (PZ) via an amplifier.
- Adjustment and measurement takes a total of approx. 3 seconds, then only the LCD display (L) and the thermobimetal 1 (E) on the disinfection mechanism are switched on.
- the liquid crystal display (L) shows the last result constantly above Hours on.
- the strength of the ultrasound is thus set up so that its energy is not sufficient to detach the specific bonds but to detach the non-specific ones.
- Ultrasound has two tasks here, firstly the acceleration of the reaction for specific bonds and secondly the prevention of non-specific bonds (adsorption).
- the simple logic circuit now decides which additional LCD display appears on the mini biosensor.
- the seven-digit display of zeros or ones corresponds to the seven measuring points, a "1" means a positive single test, etc.
- the electronics consist of the usual individual elements already mentioned, which are connected to one another with the aid of a control circuit. The whole is powered by a 3 volt battery (50mAh) (BA).
- BA 3 volt battery
- the biosensor only needs one drop (50 ⁇ l)
