This newspaper, Tel Aviv, October 17 (Reporter Putian) is in a large public place such as supermarkets, theaters and conference halls. If terrorists use vents, flue pipes or air-conditioning pipes to apply harmful gases such as anthrax, The consequences will be unimaginable. In response to this terrorist attack, a high-tech Israeli company is developing a bio-detector that can detect the type of harmful gas in real time, like a smoke detector installed on the top of the room for detecting smoke concentrations. Alert to prevent bioterrorism attacks.
Kenan, chief scientist of Bio Alarm Systems, a biodetector, said that an important technical challenge in developing biodetectors is how to properly address the balance between sensitivity and selectivity of the detector. On the one hand, the detector needs to detect the huge harm that may exist according to the minimum number of biological samples in the detection gas, which is the sensitivity of the detector; on the Other hand, to prevent the occurrence of false alarms, because in the air There is a small amount of harmful biological material, and the detector cannot issue a false alarm, which is its selectivity. According to the introduction, the bio-detector BAS101 developed by the company not only has the characteristics of rapid and accurate detection, but also has high sensitivity, can work continuously, weighs only 10 pounds, and has low maintenance cost. “It can not only alert people of harmful terrorist attacks in the air, but also tell people what types of pests they are, so that they can save time by taking effective measures.â€
生物 Most of the bio-detectors currently in use are bulky and expensive. They are generally only used in military facilities and are difficult to use in civilian facilities such as supermarkets and office buildings. Therefore, there is no effective technical means to prevent possible biological activities in large public places. Terrorist attacks. According to Israel's 21st Century Network, Kainan, a former immigrant from the former Soviet Union, developed the BAS101 three years ago and has been continuously testing and improving. It has already achieved success in the laboratory. Currently, the company is negotiating with some large companies in the US and Europe to bring the technology products to market as soon as possible.
