英國Applied Nanodetectors（AND）
英國Applied Nanodetectors（AND）試制出通過吹氣即可檢測各種疾病的手機，并在“國際納米技術綜合展（nano tech 2009）”上進行了展出。手機由芬蘭諾基亞制造。AND希望與日本通信運營商共同開展業務。該手機配備了AND開發的集成傳感器的芯片，該傳感器可檢測二氧化碳（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，檢測出各種氣體的成分，然后按強度制成矩陣圖。通過將其結果與各種疾病的特征相對照，便可檢測疾病等。對照時就像“對照指紋一樣”（AND執行董事Victor Higgs）。該公司表示，該手機可以檢測哮喘、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。雖然市面上已經銷售檢測口臭程度的終端，但利用1枚芯片能夠檢測如此之多的項目，并將其安裝在手機上，在全球尚屬首例。手機檢測出以上疾病及異常等情況之后，可自動向機主或經常就診的醫生等發送信息，從而盡快發現病情。不過，在歐洲上市該手機的時間尚未確定。“在歐洲，手機廠商勢力較強，因此我們事先與諾基亞進行了交涉。而日本的通信運營商強勢，所以我們希望與其共同開展業務。如果在日本達到實用水平，擴展到整個亞洲就只是時間的問題了”（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.
