Abstract : Thioctic acid (TA) functionalized gold nanorod (GNR) is developed as a sensor for rapid and highly sensitive
detection of AsIII at very low concentration in water and on paper substrate. GNR@TA sensor is synthesized by simple
chemical conjugation of gold nanorod with thioctic acid. GNR@TA shows visible color change in presence of AsIII in
solution and on paper strip, because of aggregation of nanorods. This method for arsenic sensing is highly selective and
showed a detection limit of ~1.0 ppb. Sensing of arsenic is also carried on paper strip suggesting usefulness of sensor under
field-test mode for arsenic sensing
