“…Anticancer drugs, such as FLD, can be extremely toxic, and this is alarming in terms of the health of aquatic species, impacting on their reproductive endocrine systems . FLD sensors have previously been reported, including sensors fabricated from different oxide phases, such as nickel oxides, molybdenum oxides, and cobalt oxides, − and various sensors that employ graphene or reduced graphene oxide. − However, the sensing of FLD with WS 2 or any WS 2 -based composite material has not been reported.…”
