Researchers from the Indian Institute of Technology, Delhi, turn to a tiny species of venomous spider called Lachesana tarabaevi in the search for compounds with anti-microbial properties. They show that peptides derived from the spider’s venom is effective against Staphylococcus aureus.
By precisely tuning the metamaterial structures, researchers create a near-perfect light trap synchronised with molecular vibrations, paving the way for advanced sensors and optical devices.
