Embodiment Construction

[0015] The following examples are intended to illustrate the present invention without further limiting the invention.

[0016] see figure 1 with figure 2 The silk-screen sensor shown includes a bottom plate 6 , a wire 1 , a working electrode 3 , a reference electrode 2 , an auxiliary electrode 4 , an insulating layer 5 , double-sided adhesive tape 7 , and a hydrophilic cover plate 8 .

[0017] The bottom plate of the screen printing sensor is made of 0.5mm PET film; the wire 1, the working electrode 3, and the auxiliary electrode 4 are all screen printed with conductive carbon paste (polu-10, Shenzhen Baolai Sheng Company). The reference electrode 2 is screen-printed with conductive silver chloride paste (JLL-1000 series, Shanghai Julong Electronic Technology Co., Ltd.), and the insulating layer 5 (AC-3G green insulating ink, produced by Jujo, Japan) is screen-printed. become. The siphon tank is assembled by double-sided adhesive tape and a hydrophilic cover.

Abstract

The invention discloses a method for quickly determining lead content in blood. A printing sensor, a blood treating fluid and a self-made electro-chemical analyzer are used in the method. The printing sensor is composed of a one-off screen-printed electrode, a double faced adhesive tape and a hydrophilic cover board. The method is used for determining the lead content in blood, has the characteristics of being sensitive in response, short in detection time, low in manufacturing cost, convenient and simple, does not need operation by a professional person, demands extremely few blood samples, and is suitable for clinical tests in hospitals and communities.

Description

technical field [0001] The invention belongs to the field of biochips, in particular to a method for detecting lead content in blood. Background technique [0002] Lead is a heavy metal element that widely exists in nature. It is soft and silver-gray, has a low melting point and is corrosion-resistant. Its compounds can show pink, yellow and other colors. It is widely used in battery, power electronics, printing, petrochemical, paint, pigment, plastic, rubber, and even food industries. Lead is a kind of toxin to our human body. Once it enters the body, it will have toxic effects on various systems and organs of the whole body. Currently, an average of 500,000 tons of lead is used in various industries in developing countries every year. Therefore, if the environmental protection system is a little poor, the lead will pollute our daily environment along with industrial waste gas, waste water, waste residue and other ways, endangering each of us. [0003] Lead poisoning is ...
