Cellphone converts into powerful chemical detector


Share post:

A  cell phone turns into a sophisticated scientific device that can identify chemicals and various drugs.

 CELL PHONES ARE USEFUL: The quality of cameras has increased exponentially over the past decade. Scientists have trained a cellphone camera to perform spectroscopy, turning the handheld device into a chemical detector, capable of identifying drugs.

Latest cell phones include high-quality cameras that detect low levels of light, this technique is really helpful as the research has used this sensitivity to manufacture mobile phone cameras which can be used as heart rate detectors and microscopes.



  • The current advance is based on two types of spectroscopy. One type, known as fluorescence spectroscopy, measures the fluorescent light emitted by a sample.
  • Another, known as Raman spectroscopy, is useful for detecting molecules, such as DNA and RNA, Both types were used to develop this cellphone detector.

For an experiment, scientists chose carrots for this study because it contains pigment carotene as they studied a variety of samples using the cellphone detector, including common solvents such as methanol, ethanol and many more.

Though, this System is a really expensive but accurate tool for detecting chemicals and pathogens in the field.


While the researchers said that their gadget gives dependable method for detecting chemicals and pathogens.

Whereas the researchers did not say something about this dangerous disease,coronavirus , but it reminds us of this five-cent sensor that detects coronavirus and immunity in just 10 minutes.

As long as I know, this  technique will bring a change in the current situation of our country and these techniques analyze the unique ways light interacts  with certain materials


  • Scientists have developed an extension to an ordinary cellphone chemical that makes drugs, biological molecules, and pathogens.
  • The development is based on fluorescence spectroscopy and Raman spectroscopy and uses the high-quality cameras found in modern cellphones.
