The conference has partnered with Electroanalysis from 2005, resulting in five special conference issues that were published in this journal (http://www.matrafured-conference.bme.hu/node/15). For this event, Electroanalyis has offered to publish a special issue that reflects the broad scope of the conference to comprise most aspects of chemical sensing. All participants with accepted oral or poster presentations at this conference are therefore invited to submit a paper for potential publication in the special issue Matrafured’19 of this journal. The submitted manuscripts will be subject to the regular peer review procedure. The submission page is at http://www.editorialmanager.com/elan, and the authors should select Mátrafüred 2019 in the Section/Category menu. The manuscripts should be submitted by October 15th, 2019 and will be subject to the regular peer review procedure of the journal.
