The triple bond between C and N in cyanide, with its characteristic band at ∼2133 cm −1, is an excellent case for the SERS-based detection due to the infrequent occurrence of triple bonds in nature. For early PA detection in CF children not yet chronically lung infected a non-invasive Surface-Enhanced Raman Spectroscopy (SERS)-based breath nanosensor is being developed. Hydrogen cyanide (HCN) at ppb level has been reported to be a PA biomarker. Due to its ready adaptation to the dehydrated mucosa of CF airways, PA infections tend to become chronic, eventually killing the patient. ![]() Lung infections with Pseudomonas aeruginosa (PA) is the most common cause of morbidity and mortality in cystic fibrosis (CF) patients.
