Special Issue Information

Dear Colleagues,

In recent years, the demand for high-efficiency biomaterials to improve various industrial applications has grown rapidly. Nanomaterials play an essential role in the scientific and technological research into the generation, processing, and fabrication of various materials and involves many disciplines while providing a remarkable range of applications from healthcare to electronics, including drug delivery systems, product development, etc. These materials will soon impact millions of lives. To move the nanobiomaterial field forward, it is crucial to develop an understanding of the impacts, toxicity, remediation, sensing, environmental impact, and food safety of different nanoparticles, as well as to conduct biological analyses to elicit potential responses by these nanomaterials. This will facilitate various technological developments in biomaterials, furthering the goal of combining nanomaterial research with applications in biosciences, engineering, materials science, and neuroscience.

This Special Issue focuses on all aspects of bionanomaterials, including the fundamentals, computations, applications, and perspectives. We invite authors to contribute review articles, original research articles, and short communications covering potential topics that involve bionanomaterials, including (but not limited to) novel approaches to the types, synthesis, characterization, functionalization, and properties of nanostructured materials; applications of nanoparticles in biomedicines; pharmaceuticals; nanotoxicity; nanoelectronics; polymers; and nanosensors and nanodevices.

We look forward to receiving your contributions.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.

Capparis zeylanica leaf extract was employed in this work to create iron oxide nanoparticles (α-Fe2O3) using anhydrous ferric chloride. The UV spectrum, XRD, FT-IR, and FE-SEM with EDX methods were used to characterize the fabricated nanoparticles. The iron oxide nanoparticles obtained were spherical in form, with an average crystallite size of 28.17 nm determined by XRD. The agar well diffusion method was used to assess the antimicrobial activity of the α-Fe2O3 nanoparticles created in this study against pathogenic organisms, Gram-negative bacteria (Escherichia coli and Pseudomonas aeroginosa), Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes), and fungi (Candida albicans and Aspergillus niger). Among the pathogens tested, S. pyogenes had the highest zones of inhibition (25 ± 1.26 mm), followed by S. aureus (23 ± 0.8 mm), E. coli (23 ± 2.46 mm), P. aeroginosa (22 ± 1.86 mm), C. albicans (19 ± 2.34 mm) and A. niger (17 ± 3.2 mm). The substance was further tested for anticancer activity against A549 (lung cancer) cells using the MTT assay. The cytotoxic reaction was found to be concentration-dependent. The present study, therefore, came to the conclusion that the bio-effectiveness of the manufactured α-Fe2O3 nanoparticles may result in applications in biomedical domains. Full article
