摘要： A lignin-zinc oxide nanohybrid may be formed by sonication of isolated lignin derived from Phoenix dactylifera biomass in an aqueous solution of a soluble zinc salt. The lignin-zinc oxide nanohybrid emulsion or nanoemulsion may then be formed by mixing the lignin-zinc oxide nanohybrid with oil and a stabilizing surfactant and sonicating. The lignin-zinc oxide nanohybrid emulsion effectively bocks UV radiation across the UV spectrum and might therefore be used for UV protection as a sunscreen.

摘要： The fabrication of nanostructures from fish waste is a method of co-fabricating C-dots and hydroxyapatite from fish scales. The method includes hydrothermal treatment of fish scales to simultaneously produce hydroxyapatite nanostructures and C-dot nanostructures. The C-dots may be used as probes for fluorescent imaging. The hydroxyapatite nanostructures may be used for tissue engineering applications.

摘要： The method for producing noble metal nanocomposites involves reducing noble metal ions (Ag, Au and Pt) on graphene oxide (GO) or carbon nanotubes (CNT) by using Artocarpus integer leaves extract as a reducing agent. As synthesized MNPs/GO and MNPs/CNT composites have been characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) imaging, and energy dispersive X-ray spectroscopy (EDX). The TEM images of prepared materials showed that the nanocomposites were 1-30 nm in size with spherical nanoparticles embedded on the surface of GO and CNT. This synthetic route is easy and rapid for preparing a variety of nanocomposites. The method avoids use of toxic chemicals, and the prepared nanocomposites can be used for biosensor, fuel cell, and biomedical applications.

摘要： The method of fabricating biocompatible cellulose nanofibrils produces cellulose nanofibrils from used agro-waste Borassus flabellifer leaf stalks. The method uses a three-step process, including alkali treatment, bleaching, and acid hydrolysis to produce cellulose nanofibrils, which may be converted to pellets for storage. The pellets may be converted to a transparent film for cell attachment by dispersion in water and heating in a hot air oven. Testing shows that cellulose nanofibrils made by the method easily attract human mesenchymal stem cells and will be applicable for skin tissue engineering applications.

摘要： The method of making a three-dimensional scaffold for three-dimensional cell culture includes obtaining amorphous silica from sorghum husks, producing biogenic silica microbodies from the amorphous silica, and clustering the biogenic silica microbodies to form the three-dimensional scaffold. The three-dimensional scaffold can be used for growing three-dimensional cell cultures, such as human mesenchymal stem cell cultures.

摘要： A method of producing biogenic silica nanoparticles comprises pretreating seed hulls of a biogenic source with an acid to form acid-treated seed hulls; placing the acid-treated seed hulls in an autoclave at a temperature greater than 100° C. for about 2 hours under a fixed pressure; isolating the seed hulls; washing the seed hulls with water; air drying the seed hulls; calcining the seed hulls at a temperature range of 500° C. to 700° C. for at least one hour in a furnace to produce biogenic silica nanoparticles. The biogenic silica nano-particles are amorphous and biocompatible possessing a particle sizes in the range of 25-75 nm.
