Special Issue Information

Dear Colleagues,

Over recent decades, there has been a seismic shift in the understanding and development of nanotechnologies for numerous applications ranging from engineering to medicine. In the food industry, nanotechnologies have become commonplace in nearly all components of the industry, including packaging, production, ingredients, storage, and even sensors. In particular, nanotechnologies have demonstrated significant contributions to food safety through the development of antimicrobial packaging, sensors for detection of food-borne pathogens, advanced sterilization techniques, and antimicrobial ingredients. While there are still significant concerns about the consumption of engineered nanomaterials, natural nanomaterials in the form of plant and animal products, nanoemulsions, etc. have always been present in the food supply. In order to demonstrate the impact of nanotechnologies for food safety, it is important to delineate the numerous contributions of nanotechnology, in its various forms, to improve the safety of our food supply.

As such, I invite researchers developing nanotechnologies to increase the safety of our food supply to submit original research articles, as well as review articles, to this Special Issue, in order to provide the readers of Nanomaterials with an updated perspective on the state of the field. Research may include any aspect of nanotechnology related to food safety, including, but not limited to, antimicrobial packaging, nanosensors for detection of foodborne pathogens, antimicrobial nano-scale ingredients, or nanotechnology-derived sterilization techniques.

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 papers will be 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. Nanomaterials 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 2000 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.

Titania/electro-reduced graphene oxide nanohybrids (TiO2/ErGO) were synthesized by the hydrolysis of titanium sulfate in graphene oxide suspension and in situ electrochemical reduction. It provides a facile and efficient method to obtain nanohybrids with TiO2 nanoparticles (TiO2 NPs) uniformly coated by graphene nanoflakes. TiO2/ErGO nanohybrids were characterized by transmission electron microscopy, X-ray diffraction, cyclic voltammogram, and electrochemical impedance spectroscopy in detail. Compared with pure ErGO and TiO2 NPs, TiO2/ErGO nanohybrids greatly enhanced the electrocatalytic activity and voltammetric response of Allura Red. In the concentration range of 0.5–5.0 μM, the anodic peak currents of Allura Red were linearly correlated to their concentrations. However, the linear relationship was changed to the semi-logarithmic relationship at a higher concentration region (5.0–800 μM). The detection limit (LOD) was 0.05 μM at a signal-to-noise ratio of 3. The superior sensing performances of the proposed sensor can be ascribed to the synergistic effect between TiO2 NPs and ErGO, which provides a favorable microenvironment for the electrochemical oxidation of Allura Red. The proposed TiO2/ErGO/GCE showed good reproducibility and stability both in determination and in storage, and it can accurately detect the concentration of Allura Red in milk drinks, providing an efficient platform for the sensitive determination of Allura Red with high reliability, simplicity, and rapidness.
