Abstract
Optički senzori zbog svojih neminovnih prednosti kao što su jednostavnost izvedbe, mjerenje u realnom vremenu, male dimenzije te niža cijena počinju zamijenjivati tradicionalne metode i zahtjevne instrumentalne analitičke metode. Mogućnost prijenosa senzora na teren, uz potrebe malih količina uzoraka i detektiranje golim okom posebice je važno u zdravstvu, analizi pitke vode i uvjetima ograničenih resursa. S obzirom na sve veću osviještenost o zagađenosti okoliša kao i ekcesivno korištenje sintetskih materijala koji predstavljaju određenu opasnost kontaminacije, javlja se potreba za korištenjem jestivih i prirodnih komponenti u senzorskim uređajima. Svoju primjenu u takvim senzorima nalazi kurkumin, pigment izdvojen iz kurkume, koji osim optičkih ima i značajna farmaceutska svojstva, zbog kojih se konzumira već više od dvjesto godina. Zahvaljujući svojoj strukturi, kurkumin podliježe kiselo-baznim reakcijama i reakcijama kompleksiranja, što rezultira optički uočljivim promjenama u pH senzorima ili drugim ion-selektivnim optodama. U ovom radu okarakterizirana su kemijska i fotofizikalna svojstva kurkumina te je predstavljen pregled izvedbi senzora temeljenih na biorazgradivim materijalima, koji uključuju kurkumin.
Abstract (english)
Optical sensors are starting to replace traditional analytical methods that use sophisticated instruments because many of their advantages, i.e. simplicity, real-time monitoring, small dimensions and lower cost. Possibility of using senors on the field, demand for smaller sample quantities and naked eye detection are especially important in healthcare, drinking water analysis and in conditions of limited resources. Given the rise of the environmental awareness and the excessive use of synthetic materials that might represent a certain contamination risk, there is a need for using edible and natural components in sensoring devices. In such sensors, curcumin could be used. Curcumin is a pigment, extracted from tumeric, that yields significant pharmaceutical properties, which because of it has been consumed for over two hundred years. Because of its structure, it can exhibit keto-enol tautomerism, which leads to deprotonation, and can undergo complexation with specific ions. Those reactions can make changes in optical properties in pH sensors or other ion-selective optodes. This work discusses chemical and photophysical properties of curcumin and reviews sensor platforms made of biodegradable materials, including curcumin.
