Synthesis of graphene quantum dots and their applications in drug delivery

“…In recent years, the applications of GQDs in drug delivery [123][124][125][126][127], sensors [128][129][130][131][132][133][134], bio-imaging [10,63,[135][136][137][138][139][140], magnetic hyperthermia [141][142][143], photothermal therapy [144][145][146][147][148], antibacterial [145,149,150], catalyst [69,[151][152][153][154][155], environmental protection [38,156,157], and energy [158][159][160][161][162][163] has made remarkable accomplishment. In order to better apply GQDs to drug delivery, some researchers had used density functional theory (DFT) calculations [164]…”

A comparative study on the photocatalytic degradation of organic dyes using hybridized 1T/2H, 1T/3R and 2H MoS2 nano-sheets

“…25 As an efficient semiconducting nanomaterial, MoS 2 has been employed in environmental engineering, for treatment of organic pollutants via both, adsorption or photo-catalytic degradation. [33][34][35][36][37][38][39][40] MoS 2 is, however, a very delicate semiconducting material. The factors affecting its electronic structure and, hence, properties are quite various, including the molybdenum local coordination environment, the sulphur vacancies and surface defects, the crystal phase (1T, 2H or 3R) with different conductivities, as well as the degree of exfoliation, and the size and morphology of the nano-sheets.…”

“…This wide variety of factors affecting the molecular and electronic structure as well as active surface area has led to several contradicting reports about the adsorptive and photo-catalytic properties of the material, probably due to neglecting the effect of the actual phase of the material. [33][34][35][36][37][38][39][40] Fast and efficient adsorption has been reported for MoS 2 and several of its nanocomposites towards different organic dyes. [33][34][35][36][37] Liu and coworkers claimed no adsorptive capabilities for their samples and attributed the improved photo-catalytic activity of leafshaped MoS 2 to its morphology and its thinner layer structure with no account on the actual phase of the material.…”
