Special Issue Information

Dear Colleagues,

Nanotechnology has emerged as a dominant force in recent industrial advancements, particularly in the realm of electronic, optoelectronic, and biomedical devices. 

Nanoelectronics lie at the intersection of nanotechnology and electronics, focusing on the development of devices at the nanoscale. Contrary to their macroscopic counterparts, these devices exhibit unique properties with unprecedented functionality and performance. Advanced functional nanomaterials in their crystalline state are pivotal in the fabrication of cutting-edge nanoelectronic devices, which hold immense potential across various sectors, notably in computing, optics, biomedical, and environmental sciences. 
This Special Issue focuses on research efforts in nanoelectronics, including nanomaterials synthesis, device design, fabrication techniques, and characterization methods, driving innovation towards practical applications in the realms of biotechnology, biomedicine, and healthcare. We encourage industrial and academic scientists to submit their experimental and theoretical results in the form of original articles, review papers, and short communications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study explores the development of an electronic nose (E-nose) sensor for fish freshness based on a composite of polyvinyl alcohol (PVA), polyethylene glycol (PEG), and reduced graphene oxide (rGO). The sensor leverages the unique properties of the PVA-PEG polymer matrix, such as its flexibility and moisture responsiveness, in combination with the electrical conductivity of rGO. The PVA-PEG/rGO composite was synthesized through a low-temperature embedding process to ensure the preservation of sensitive biomolecules and prevent thermal degradation. This sensor demonstrates high sensitivity to volatile amines released during fish spoilage, providing real-time food monitoring to maintain freshness. Electrical resistance changes in the rGO network, influenced by the polymer’s interaction with spoilage gases, were correlated with fish freshness levels. The low cost, easy fabrication, and environmentally friendly nature of the PVA-PEG/rGO E-nose sensor make it a promising candidate for use in packaging or direct contact with fish products in the food industry. This study highlights the potential for extending shelf life and reducing food waste through rapid spoilage detection. Full article
