Abstract

Kemijski senzori i biosenzori su uređaji koji imaju široku primjenu u svakodnevnom životu, znanosti i industriji. Kemijski senzor je analitički uređaj koji pretvara određenu kemijsku informaciju u analitički mjerljiv signal. Optički kemijski senzor detektira promjenu optičkih svojstava koja je posljedica njegove interakcije s analitom. Povećan interes za primjenu ovih senzora opravdana je brojnim prednostima: jednostavnost uporabe, ekonomičnost, brzina odziva, osjetljivost i selektivnost. U novije se vrijeme tekstil i papir sve češće koriste kao matrice za primjenu u optičkim kemijskim senzorima zahvaljujući pristupačnosti, ekonomičnosti, netoksičnosti i sposobnosti regeneracije. Celuloza, koja sačinjava tekstil i papir, omogućuje protok tvari kroz matricu kapilarnim silama, stoga ove materijale čini idealnima za senzorsku primjenu. U ovome radu naveden je pregled optičkih kemijskih senzora i biosenzora na tekstilu i papiru za detekciju različitih analita (pH, glukoza, amonijak, vodikov peroksid, cijanidni anion, živin (II) kation i drugi). Optički kemijski senzori na bazi tekstila i papira pokazuju veliki potencijal za primjenu zahvaljujući brojnim prednostima.

Abstract (english)

Chemical sensors and biosensors are devices with wide application in everyday life, science and industry. Chemical sensor is an analytical instrument that converts specific chemical information in analytically measurable signal. Optical chemical sensor detects changes in optical properties resulting from its interaction with analyte. Increased interest in their application is result of their simplicity, fast response time, sensitivity and selectivity. Lately, textile and paper have been more often used as matrices for application in optical chemical sensors due to their accessibility, non-toxicity and ability to regenerate. Cellulose, the main component of textile and paper, enables flow of the substances through matrix by capillary action making these materials adequate for optical chemical sensing. In this paper, some optical chemical textile-based and paper-based sensors and biosensors are shown according to type of detected analytes (pH, glucose, ammonia, hydrogen peroxide, cyanide anion, mercury (II) cation and other). Textile-based and paper-based optical chemical sensors show great potential in application thanks to numerous advantages.
