Uporaba mikrovalov pri intenzifikaciji procesov v mikrofluidnih napravah

Močnik, Žan (author), Plazl, Igor (mentor)

Na področju mikrofluidike je v zadnjem desetletju opaziti večje zanimanje za implementacijo mikrovalov v mikrofluidne sisteme. Oboji izkazujejo intenzifikacijo mnogih procesov zaradi lastnosti opisanih v tretjem in četrtem poglavju. V petem poglavju sledi pregled dognanj na področju vnosa toplotne energije v mikrofluidne sisteme z različno konstruiranimi aplikatorji mikrovalov in primerov uporabe mikrovalov za vodenje reakcij v mikroreaktorjih. V šestem poglavju so opisana dognanja na področju analize bioloških vzorcev z mikrovalovi v mikrofluidiki. Poglavitna prednost mikrovalov je brezkontaktno gretje in hkrati merjenje različnih karakteristik obsevane snovi. Mikrofluidni sistemi izkazujejo skoraj takojšnji odziv na spremembo v mikrovalovih, zato je posebej obetavno področje uporabe verižna reakcija s polimerazo, kjer je natančen nadzor temperature izjemnega pomena.

• Title: Microwave assisted process intensification in microfluidic devices

Abstract

In the field of microfluidics, there has been a growing interest in the implementation of microwaves in microfluidic systems over the last decade. Intensification of many processes is shown by usage of both, due to the properties described in third and fourth chapters. In the fifth chapter, findings in the field of heat input into microfluidic systems with differently designed microwave applicators and examples of the use of microwaves to control reactions in microreactors, are being reviewed. The sixth chapter describes the findings in the field of analysis of biological samples with microwaves in microfluidics. The main advantage of microwaves is non-contact heating and measuring various characteristics of the irradiated substance simultaneously. Microfluidic systems show an almost immediate response to a change in microwave irradiation intensity, therefore a particular promising area of application is the polymerase chain reaction, where precise temperature control is of immense importance.
