“…This investigation of the surface chemistry revealed that at 185–200 °C, the solution chemistry must be dominated by a species that promotes Cu 2– x Se growth and largely displaces the thiol ligands. Selenide ions play both of these roles, serving as ligands on metal sulfides and driving their formation. , …”

To identify the cause of the color change of the ddt/octadecene/Se reaction mixture and identify species that might form a Se-containing surface ligand, we heated the components from the reaction mixtures without nanorod injection and examined the solutions with 1 H NMR (Figures 5b and S8).…”

Rational design of elaborate, multicomponent nanomaterials is important for the development of many technologies such as optoelectronic devices, photocatalysts, and ion batteries. Combination of metal chalcogenides with different anions, such as in CdS/CdSe structures, is particularly effective for creating heterojunctions with valence band offsets. Seeded growth, often coupled with cation exchange, is commonly used to create various core/shell, dot-in-rod, or multipod geometries. To augment this library of multichalcogenide structures with new geometries, we have developed a method for postsynthetic transformation of copper sulfide nanorods into several different classes of nanoheterostructures containing both copper sulfide and copper selenide. Two distinct temperature-dependent pathways allow us to select from several outcomes�rectangular, faceted Cu 2−x S/Cu 2−x Se core/shell structures, nanorhombuses with a Cu 2−x S core, and triangular deposits of Cu 2−x Se or Cu 2−x (S,Se) solid solutions. These different outcomes arise due to the evolution of the molecular components in solution. At lower temperatures, slow Cu 2−x S dissolution leads to concerted morphology change and Cu 2−x Se deposition, while Se-anion exchange dominates at higher temperatures. We present detailed characterization of these Cu 2−x S−Cu 2−x Se nanoheterostructures by transmission electron microscopy (TEM), powder X-ray diffraction, energy-dispersive X-ray spectroscopy, and scanning TEM−energy-dispersive spectroscopy. Furthermore, we correlate the selenium species present in solution with the roles they play in the temperature dependence of nanoheterostructure formation by comparing the outcomes of the established reaction conditions to use of didecyl diselenide as a transformation precursor.

“…Under acidic pH, PGA can retain the drugs loaded inside the conjugate and quickly releases the drug at pH 6–7. The use of FeSe NPs allowed for the mapping of the biodistribution of the FeSe NPs-PGA-DOX conjugate over time in mice, and also confirmed the delivery of drugs to the target [ 32 ].…”

Nanomaterials (NMs) synthesized from natural sources have been attracting greater attention, due to their intrinsic advantages including biocompatibility, stimuli-responsive property, nontoxicity, cost-effectiveness, and non-immunogenic characteristics in the biological environment. Among various biomedical applications, a breakthrough has been achieved in the development of drug delivery systems (DDS). Biocompatibility is necessary for treating a disease safely without any adverse effects. Some components in DDS respond to the physiological environment, such as pH, temperature, and functional group at the target, which facilitates targeted drug release. NM-based DDS is being applied for treating cancer, arthritis, cardiovascular diseases, and dermal and ophthalmic diseases. Metal nanomaterials and carbon quantum dots are synthesized and stabilized using functional molecules extracted from natural sources. Polymers, mucilage and gums, exosomes, and molecules with biological activities are directly derived from natural sources. In DDS, these functional components have been used as drug carriers, imaging agents, targeting moieties, and super disintegrants. Plant extracts, biowaste, biomass, and microorganisms have been used as the natural source for obtaining these NMs. This review highlights the natural sources, synthesis, and application of metallic materials, polymeric materials, carbon dots, mucilage and gums, and exosomes in DDS. Aside from that, challenges and future perspectives on using natural resources for DDS are also discussed.
