Metal-organic frameworks

Researchers from Belgium have built a sensitive electronic nose with metal-organic frameworks (MOFs) that can detect pesticides and nerve gas in very low concentrations. 

Details:

• MOFs are like microscopic sponges. They can absorb quite a lot of gas into their minuscule pores.
• The chemical sensor can easily be integrated into existing electronic devices.
• The new MOF is the most sensitive gas sensor to date for dangerous substances.
• MOFs can measure very low concentrations, so we could use them to screen someone’s breath for diseases such as lung cancer and multiple sclerosis (MS) in an early stage.
