Uporaba grafen oksidnih kompozitov v biosenzoriki

Šandor, Tea (author), Šebenik, Urška (mentor)

Grafen-oksid je predmet številnih raziskav. Zaradi svojih izrednih električnih, optičnih in kemijskih lastnosti je njegova uporaba zelo razširjena. Eno izmed teh področij je tudi biosenzorika, kjer se je GO izkazal kot material, ki lahko doprinese k številnim izboljšavam. Raziskovanje v diplomskem delu je usmerjeno v materiale na osnovi grafen-oksida, ki se uporabljajo pri načrtovanju in izdelavi bioloških senzorjev. Biosenzorji imajo ključni pomen v medicini, klinični analizi in splošnemu spremljanju zdravja. Zato so njihove lastnosti in zmožnosti nenehno raziskujejo in izboljšujejo. V delu sem raziskovala lastnosti GO materialov in njihovo aplikacijo v bioloških senzorjih. Podrobneje sem preučila raziskave, kjer se grafen-oksid uporablja za različne vrste biosenzorjev, kot so biosenzor za zaznavo lizocima, za zaznavo rakavih celic in zaznavo patogena. Predstavljeno je tudi splošno delovanje senzorjev in njihove najpomembnejše lastnosti.

Abstract

Graphene oxide is the subject of many researches. Due to his extraordinary electrical, optical and chemical properties its use is widespread. One of the areas is also biology, where GO has proven to be a material that can contribute many improvements in biosensors. The research is focused on materials based on graphene oxide, which are used in design and manufacture of biological sensors. Biosensors are very important in medicine, clinical analysis and general health monitoring. Therefore, their properties and capabilities are constantly being researched and improved. In my work, I researched the properties of GO materials and their application in biological sensors. I studied in more detail the research where graphene oxide is used for different types of biosensors, such as biosensor fort the detection of lysozyme, for the detection of cancer cells and the detection of a pathogen. In the work there are also presented operation biological sensors and their most important properties.
