Abstract

Przedmiotem zgłoszenia jest nanorozmiarowy czujnik jonów rtęci, charakteryzujący się wysoką czułością oraz selektywnością, zbudowany z kropki kwantowej, zawierającej tellur i kadm, pokrytej warstwą polimeru sfunkcjonalizowanego tyminą, gdzie stopień podstawienia grupami tyminowymi wynosi 30 - 50%, korzystnie 41%. Czujnik charakteryzuje się wysoką selektywnością wobec jonów rtęci oraz niskim progiem stężenia jonów rtęci, koniecznym do zaobserwowania mierzalnego efektu, tj. wzrostu intensywności fluorescencji przy długości fali 550 - 560 nm. Przedmiotem zgłoszenia jest także sposób otrzymywania czujnika oraz sposób wykrywania jonów Hg2+.The subject of the application is a nanosize mercury ion sensor, characterized by high sensitivity and selectivity, built of a quantum dot containing tellurium and cadmium, covered with a layer of thymine functionalized polymer, where the degree of substitution with thymine groups is 30 - 50%, preferably 41%. The sensor is characterized by high selectivity towards mercury ions and a low concentration threshold of mercury ions, necessary to observe a measurable effect, i.e. an increase in fluorescence intensity at a wavelength of 550 - 560 nm. The subject of the notification is also the method of obtaining the sensor and the method of detecting Hg2 + ions.
