- The sensor works by analysing a tiny drop of drink as it comes into contact with a new chemical formula

A sensor that can detect date-rape drugs in drinks with an accuracy of 100 per cent has been developed by scientists.
The device works in real-time so instantly alerts the user as to whether their drink has been spiked or not.
It works by analysing a tiny drop of drink as it comes into contact with a chemical formula made by the researchers.
Date-rape danger: The device works in real-time so instantly alerts the user as to whether their drink has been spiked or not
The reaction determines whether the beverage has been spiked with either of the two most common date-rape drugs, GHB (gamma-hydroxybutyric acid) and ketamine.
Researcher Michael Ioffe, of Tel Aviv University, told AFP: 'You don't even have to hold it up to the light and the system will let you know whether there are drugs dissolved in your drink.
'The drug itself is reacting with this chemical formulation and the previously clear formula becomes dirty and when the light shines it you can detect it.
'You don't have to do anything but dip it in your drink.'
Dr Ioffe and his co-researcher Professor Fernando Patolsky were amazed to find that their formula has a 100 per cent success rate.
No matter what drink it is dipped in, be it beer, cocktails or soft drinks, the device responded with the correct answer.
The Israeli scientists are now awaiting funding in order to mass produce their invention.
But there is still work to be done. For one thing, they are undecided as to the best way for their device to alert a user to the fact their drink has been spiked.
Dr Ioffe said: 'We haven't decided how it will let you know.
'Maybe it will just light up or a part of it will rotate or maybe it will send a signal to your cell phone because you want to be discreet about it.'
