Special Issue Information

Dear Colleagues,

We warmly invite you to submit your recent work in the field of Biomaterials to the Special Issue entitled “Nanomaterials or Polymer-Based Biomaterials: Chemical Synthesis and Applications”.

At present, nanomaterials or polymer-based biomaterials play important roles in the development of medicines, and in other areas. They are either synthesized or available naturally, and have a variety of applications, such as in tissue healing and regeneration, biosensors, and drug delivery systems. Nanomaterials or polymer based-biomaterials can be constructed according to requirements, and are therefore of huge demand in the medical industry. Additionally, they have a selective action, and can be used in the healing of wounds, bone growth, skin growth, blood vessel formation, etc. If needed, biomaterials can also dissolve over time, being useful, for example, in dressings for burn victims.

Furthermore, the demand for carbon-based nanomaterials continues to increase. In the last decade, researchers have focused on graphene oxide, reduced graphene oxide, and are now moving on to graphynes. These are highly conductive materials, and are being explored for use in the areas of biomedical sciences, water remediation, and many more.

Taking into consideration the importance of biomaterials, the aim of this Special Issue is to collect state-of-the-art research papers and reviews on the different synthesis methods of biomaterials. The topics of interest include, but are not limited to, the following:

  • synthesis of biomaterials in medicine;
  • synthesis of GO, rGO, and graphynes
  • bioresponsive materials;
  • biomaterials for drug delivery;
  • hybrid biomaterials;
  • regenerative biomaterials;
  • temperature response biomaterials;
  • role of graphynes in sensors, medical fields, and material sciences;
  • graphynes as antibacterial, antiviral, and self-cleanser materials.

We look forward to your submissions and cooperation.

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. Molecules 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 2700 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Acting as a growth regulator, Indole-3-acetic acid (IAA) is an important phytohormone that can be produced by several Bacillus species. However, few studies have been published on the comprehensive evaluation of the strains for practical applications and the effects of selenium species on their IAA-producing ability. The present study showed the selenite reduction strain Bacillus altitudinis LH18, which is capable of producing selenium nanoparticles (SeNPs) at a high yield in a cost-effective manner. Bio-SeNPs were systematically characterized by using DLS, zeta potential, SEM, and FTIR. The results showed that these bio-SeNPs were small in particle size, homogeneously dispersed, and highly stable. Significantly, the IAA-producing ability of strain was differently affected under different selenium species. The addition of SeNPs and sodium selenite resulted in IAA contents of 221.7 µg/mL and 91.01 µg/mL, respectively, which were 3.23 and 1.33 times higher than that of the control. This study is the first to examine the influence of various selenium species on the IAA-producing capacity of Bacillus spp., providing a theoretical foundation for the enhancement of the IAA-production potential of microorganisms.

Our aims in this work are the preparation of an ionic liquid based on heterocyclic compounds with Ag nanoparticles and the investigation of its application as an antibacterial and anticandidal agent. These goals were achieved through the fabrication of an ionic liquid based on Ag nanoparticles with 5-Amino-3-(4-fluorophenyl)-N-hexadecyl-7-(4-methylphenyl)-2-H spiro[cyclohexane1,2’-[1,3]thiazolo [4,5-b]pyridine]-6-carbonitrile (P16). The nanostructure of the prepared ionic liquid was characterized using techniques such as FTIR, 1HNMR, 13CNMR, UV, SEM, and TEM. The biological activity of the prepared compound (P16) and its nanocomposites with Ag nanoparticles was tested using five clinical bacteria (Pseudomonas aeruginosa 249; Escherichia coli 141; Enterobacter cloacae 235; Staphylococcus epidermidis BC 161, and methicillin-resistant S. aureus 217), and three Candida species (Candida utilis ATCC 9255; C. tropicalis ATCC 1362, and C. albicans ATCC 20402). The FTIR, 1HNMR, and 13CNMR results confirmed the chemical structure of the synthesized P16 compound. The nanostructure of the prepared ionic liquid was determined based on data obtained from the UV, SEM, and TEM tests. The antibacterial and anticandidal results showed that the biological activity of the compound (P16) was enhanced after the formation of nanocomposite structures with Ag nanoparticles. Moreover, the biological activity of the compound itself (P16) and that of its nanocomposite structure with Ag nanoparticles was higher than that of ampicillin and amphotericin B, which were used as control drugs in this work.
