Special Issue Information

Dear Colleagues,

Materials that are manipulated at the nanoscale have unique properties compared to their bulk counterparts. Nanomaterials are characterized by controlled morphology and geometry, providing superior electrical, chemical, physical, and optical properties. Due to increased public health awareness, nanostructured materials are becoming increasingly used in biomedical applications. Therefore, it is important to develop the controlled synthesis of nanomaterials and characterize them using various methods to understand their molecular functions. However, safety concerns have slowed the implementation of new nanomaterials in biomedicine compared to other fields. While some nanomaterials exhibit excellent intra- and extra-cellular interactions, their biocompatibility restricts their use for therapeutic and tissue-engineering purposes. For various biomedical applications, it is crucial to select appropriate nanomaterials and understand their physiological interactions with tissues. By collaborating on nanomaterial research, biomedical applications could be expanded more rapidly.

This Special Issue of Bioengineering on Emerging Nanomaterials and Nanotechnologies for Biomedical Applications aims to gather original research papers and comprehensive reviews from global experts to review the progress made in the development of various novel nanomaterials and nanotechnologies for biomedical applications.

With the rise of antibiotic resistance, the drive to discover novel antimicrobial substances and standard testing methods with the aim of controlling transmissive diseases are substantially high. In healthcare sectors and industries, although methods for testing antibiotics and other aqueous-based reagents are well established, methods for testing nanomaterials, non-polar and other particle-based suspensions are still debatable. Hence, utilities of ISO standard validations of such substances have been recalled where corrective actions had to be taken. This paper reports a serial analysis obtained from testing the antimicrobial activities of 10 metallic-based nanomaterials against 10 different pathogens using five different in vitro assays, where the technique, limitation and robustness of each method were evaluated. To confirm antimicrobial activities of metallic-based nanomaterial suspensions, it was found that at least two methods must be used, one being the agar well diffusion method, which was found to be the most reliable method. The agar well diffusion method provided not only information on antimicrobial efficacy through the size of the inhibitory zones, but it also identified antimicrobial ions and synergistic effects released by the test materials. To ascertain the effective inhibitory concentration of nanoparticles, the resazurin broth dilution method is recommended, as MIC can be determined visually without utilising any equipment. This method also overcomes the limit of detection (LoD) and absorbance interference issues, which are often found in the overexpression of cell debris and nanoparticles or quantum dots with optical profiles. In this study, bimetallic AgCu was found to be the most effective antimicrobial nanoparticle tested against across the bacterial (MIC 7 µg/mL) and fungal (MIC 62.5 µg/mL) species. Full article
