英國(guó)Applied Nanodetectors（AND）
英國(guó)Applied Nanodetectors（AND）試制出通過(guò)吹氣即可檢測(cè)各種疾病的手機(jī)，并在“國(guó)際納米技術(shù)綜合展（nano tech 2009）”上進(jìn)行了展出。手機(jī)由芬蘭諾基亞制造。AND希望與日本通信運(yùn)營(yíng)商共同開(kāi)展業(yè)務(wù)。該手機(jī)配備了AND開(kāi)發(fā)的集成傳感器的芯片，該傳感器可檢測(cè)二氧化碳（CO2）、氮氧化物（NOx）及氨氣（NH3）等各種氣體。該芯片從呼吸的成分中，檢測(cè)出各種氣體的成分，然后按強(qiáng)度制成矩陣圖。通過(guò)將其結(jié)果與各種疾病的特征相對(duì)照，便可檢測(cè)疾病等。對(duì)照時(shí)就像“對(duì)照指紋一樣”（AND執(zhí)行董事Victor Higgs）。該公司表示，該手機(jī)可以檢測(cè)哮喘、糖尿病、肺癌、在歐洲被稱為“Gastro”的食物中毒、口臭程度及呼氣中的酒精濃度等。雖然市面上已經(jīng)銷(xiāo)售檢測(cè)口臭程度的終端，但利用1枚芯片能夠檢測(cè)如此之多的項(xiàng)目，并將其安裝在手機(jī)上，在全球尚屬首例。手機(jī)檢測(cè)出以上疾病及異常等情況之后，可自動(dòng)向機(jī)主或經(jīng)常就診的醫(yī)生等發(fā)送信息，從而盡快發(fā)現(xiàn)病情。不過(guò)，在歐洲上市該手機(jī)的時(shí)間尚未確定。“在歐洲，手機(jī)廠商勢(shì)力較強(qiáng)，因此我們事先與諾基亞進(jìn)行了交涉。而日本的通信運(yùn)營(yíng)商強(qiáng)勢(shì)，所以我們希望與其共同開(kāi)展業(yè)務(wù)。如果在日本達(dá)到實(shí)用水平，擴(kuò)展到整個(gè)亞洲就只是時(shí)間的問(wèn)題了”（Higgs）。

Nanosensors

Nanotechnology generally is defined as the creation and use of materials, devices and systems through the manipulation of matter at scales of less than 100 nanometres or 0.0000001 of a meter (i.e., about the size of three atoms). At this scale, the properties that characterize larger systems do not necessarily apply.

Nanostructured metals are generally harder than macroscale metals, nanoceramics are softer, etc. Nanoscale materials light absorption properties also differ from macroscale materials, e.g., some materials become transparent if the particles are small enough. Since many of the properties that sensors are supposed to measure are formed on the molecular or atomic level, nanotechnology has obvious sensing applications. Sensors constructed at the molecular scale would be extremely sensitive, selective, and responsive and thus, the impact of nanotechnology on sensors potentially is huge.

The technology we are proposing can be readily integrated into standard electronics circuits. The reduction in sensor size can result in lower cost of materials, lower power consumption and reduced weight which are key drivers for these sensors in the marketplace. These types of sensors with reduced power consumptions are ideally suited for wireless communication devices to facilitate monitoring and control. Such low powered devices are also suitable for battery operated wearable sensors. This enables the technology to be developed initially from a simple portable device to a miniaturised version which could be incorporated in to a mobile phone or even a portable digital assistant (PDA).

Nanosensors manufactured at the molecular and nanoscale and are going to be very sensitive, selective, responsive. Technological improvements in microelectronic technologies, surface science, and signal processing have contributed enormously to the evolution of sensors. Unlike the bulky and expensive traditional sensors, the new miniscule nanosensors can help lower materials cost, weight, and power consumption in manufacturing processes. Nanofabricated sensors can be mounted on a wireless package, which eliminate wiring and cabling costs. Integration of multiple sensing technologies into a single smart chip will greatly drive down manufacturing costs. The ability to build objects with molecular precision is will revolutionize manufacturing, allowing great improvements in material properties and device performance.
