Soft chemistry of metastable metal chalcogenide nanomaterials

Abstract

This review summarizes the latest advances in design principles based on metastable metal chalcogenide nanomaterials (MCNs), together with corresponding soft chemical transformation rules to prepare or modify MCNs with novel or enhanced properties.

Recent Progress on Molecular Photoacoustic Imaging with Carbon-Based Nanocomposites

“…The GDY sheets can be encapsulated with polyethylene glycol (PEG) via intermolecular electrostatic interactions, which results in the nanocomposite GDY-PEG (Figure 13b); the materials show biocompatibility and efficient photothermal ablation of cancer cells in response to laser irradiation at 808 nm. Similarly, other 2D materials such as metal chalcogenides or MXenes that have recently received attention are thought to provide the platform for formulating theragnostic agents similar to GDY or RGO sheets, which then may have synergistic or enhanced photophysical properties [120][121][122]. Metal-organic frameworks (MOFs) have provided a platform for the formation of carbon nanocomposites which are used in bio-imaging and phototherapy.…”

Engineering of a self-supported carbon electrode with 2D ultrathin heterostructures of NiCo LDH/NiCoS via a MOF-template for sensitive detection of glucose and H2O2

“…15,16 In particular in the interior of nanomaterials, it is easy to construct a multi-component heterogeneous interface in the process of ion exchange with S 2− , which promotes the reduction of the surface energy of the material. 17 Since the electrochemical reaction of TMS always occurs on the surface or interface of an electrode material, and the ultrathin structure of the TMS material has abundant specific surface areas and defects, it can provide more active sites for electrochemical sensing. For example, the NiS nanoparticles prepared by electrodeposition showed excellent redox properties for glucose and H 2 O 2 , reaching sensitivities of 25.71 and 0.498 μA μM −1 with detection ranges of 1–1000 and 1–5000 μM.…”

Viscoelasticity Investigation of Semiconductor NP (CdS and PbS) Controlled Biomimetic Nanoparticle Hydrogels

“…Because of the charming performance exhibited by materials as they progress from the atomic to the molecular scale and approach extended solids, soft matter fabricated from various metal and semiconductor NPs in colloidal suspensions has gained considerable attention in recent decades ( Boles et al, 2016 ; Li et al, 2021 ; Mao et al, 2016 ; Scalise et al, 2018 ; Al˗Johani et al, 2017 ; Algar et al, 2019 ; Love et al, 2015 ; Gu et al, 2021 ). Colloidal nanoparticles (NPs), a kind of soft matter, formed by water-soluble inorganic nanoparticles, have been demonstrated to afford an opportunity to merge the nanoscale world with macroscopic-sized materials that can be readily processed and operated while retaining nanoscale performance ( Kotov and Weiss, 2014 ; Bhattacharya and Samanta, 2016 ; Yip et al, 2019 ).…”
