In a new study, researchers at the Indian Institute of Technology Bombay, have designed a biosensor using gold nanoparticles that can identify the presence of a protein called alpha-synuclein.  The newly developed biosensor uses optical fibres to identify these proteins even in very low concentrations and can do so in just 15 minutes of time.

Cancer is a difficult disease, both for patients and doctors. One of the many side effects of cancer therapies is secondary infections that are caused by a weakened immune system. Current strategies for treating bacterial infections in cancer patients have many drawbacks. Addressing these issues scientists from the Indian Institute of Technology, Delhi show that administering antimicrobial medicines with gold nanoparticles increases their efficacy by upto 40%.
