What is it about?
The stated long-termgoal is to manufacture and use magnetically functionalized, biocompatible micro- and nano-containers with customised properties and a defined effect achieved by adding agents such as therapeutic or diagnostic agents. The magnetic filling has a dual function both for the hyperthermal effect and counting the number of containers using magnetic sensors. A transfer printing process is developed for the fabrication of thin film magnetic sensor systems using a new type of water-soluble sacrificial layer – uncured polyvinylpyrrolidone (PVP). The performance of transfer printed magnetic sensors on PEEK foil has comparable values that were achieved and sometimes even exceeded on Si substrates.

Why is it important?
The transfer printing process developed is of a general nature and can be applied to other thin film systems and complete electronic components. The transferred sensors are used to count magnetically functionalised containers consisting of Fe-filled carbon nanotubes in a polymeric matrix. A detection rate of higher than 91% was achieved.
Perspectives
As evaluated and commented by referees, our transfer printing process is even suitable for large scale industrial production.
