Special Issue Information

Dear Colleagues,

The development of nanomaterials such as nanoparticles, nanotubes, and nanoplatelets has inspired more and more nanocomposites with polymeric, metallic or ceramic matrices. The addition of nanomaterials may give the matrix material new characteristics and new functions. One potential field of application is medical implants and tissue engineering, such as dental implant, hip/knee joint, bone cement, bone graft, implantable monitoring/drug delivery devices or scaffolds for tissue engineering. Ceramic nanoparticles or nanotubes are often used as reinforcement and a bioactive agent in polymeric or cement nanocomposites. Nanocomposite materials can be used as a coating material as well as bulk material. Metallic implants usually lack compatibility with live tissues, which can be improved with a nanocomposite coating for antibacterial property and biocompatibility. More applications are emerging in other industries, where there is a strong demand for anti-fouling and photocatalytic materials to protect against microbial buildup and toxic organic substances.

There are a few points that still need to be addressed before these new materials can be applied by practitioners, which include production and standardization of nanomaterials, achievement of good dispersions in matrices, processing of nanocomposites to achieve desirable mechanical properties, and interaction with the biological/living environment. Extensive investigation is being done to address these issues to take nanocomposite materials into industrial applications.

The aim of the contributions to this volume will be to report advances in the design and processing of nanocomposite materials, our understanding of the interface of nanomaterials with different types of matrices, and how these composite materials interact with microbes or toxic organic matter in the environment. Advances in the development of nanocomposite scaffolds for tissue engineering (such as ligament, tendons, etc.) and research on nanocomposite architecture and biointeractions with great potential to open the door to clinical or industrial applications are particularly encouraged in this Special Issue. Both original articles and topical reviews are welcome.

Green synthesis has recently attracted extensive attention from scientists all over the world for the production of metal nanoparticles. Selenium nanoparticles (Se NPs) have been demonstrated as a suitable supplement nutrient for the replacement of selenium ions in terms of safety and efficiency. This work presented a friendly and facile approach to synthesize the Se NPs using polyphenols content in the Cleistocalyx operculatus (CO) leaves extract. The synthesizing conditions were optimized to obtain the Se NPs with uniform distribution and shape. The prepared Se NPs were well-characterized using scanning electron microscopy, X-ray diffraction, energy diffractive spectroscopy, and Fourier-transform infrared spectroscopy. The resultant Se NPs were in spherical shape with the particle size in a range from 50–200 nm. The antimicrobial properties of Se NPs were investigated against Echerichia coli and Staphylococcus aureus, which showed reasonable activity. The acute oral toxicity of Se NPs in mice was also studied. The result indicated that Se NPs exhibited lower toxicity than that of SeO2 with the lethal concentration (50% death of mice) of 7.75 mg kg−1. Full article

A method was developed for the conjugation of aminopropyl spacer-bearing carbohydrates with epoxy groups on the crown of nanoparticles consisting of a copolymer of N-vinyl-2-pyrrolidone and allyl glycidyl ether in basic buffer, opening prospects for the design of vectorized nanocomposite drug forms. A conjugate of the above copolymer and trisaccharide A, a synthetic blood group antigen, was synthesized. Meglumine was used to bind any unreacted epoxide groups of the allyl glycidyl fragment. One- and two-dimensional NMR spectroscopy showed quantitative opening of the epoxide ring as a result of carbohydrate immobilization. By integrating the characteristic signals in the 1H NMR spectrum, we determined the molar ratio of the immobilized vector and meglumine, as well as the composition and number-average molecular weight of the carrier copolymer. The results obtained point to the interesting possibilities in the further study of the polymer–carbohydrate ligand system as a platform for the development of several drug carriers and theranostics based on them.
