“…2 NPs, particularly owing to their high surface area, exhibit distinctive features that determine the engineering of biological interactions. 3 In this regard, it is very critical to understand NP interaction at cellular and subcellular status. Also, NPs can be used as drugs to induce antiproliferative activity against cancerous cells.…”

BackgroundRecently, nanomaterials have moved into biological and medicinal implementations like cancer therapy. Therefore, before clinical trials, their binding to plasma proteins like human serum albumin (HSA) and their cytotoxic effects against normal and cancer cell lines should be addressed.MethodsHerein, the interaction of magnesium oxide nanoparticles (MgO NPs) with HSA was studied by means of fluorescence spectroscopy, circular dichroism (CD) spectroscopy, and docking studies. Afterwards, the cytotoxic impacts of MgO NPs on human leukemia cell line (K562) and peripheral blood mononucleated cells (PBMCs) were evaluated by MTT and flow cytometry assays to quantify reactive oxygen species (ROS) generation and apoptosis.ResultsIt was demonstrated that MgO NPs spontaneously form a static complex with HSA molecules through hydrophobic interactions. Docking study based on the size of NPs demonstrated that different linkages can be established between MgO NPs and HSA. The CD investigation explored that MgO NPs did not alter the secondary structure of HSA. Cellular studies revealed that MgO NPs induced cytotoxicity against K562 cell lines, whereas no adverse effects were detected on PBMCs up to optimum applied concentration of MgO NPs. It was exhibited that ROS production mediated by IC50 concentrations of MgO NPs caused apoptosis-associated cell death. The pre-incubation of K562 with ROS scavenger (curcumin) inhibited the impact of MgO NPs -based apoptosis on cell fate, revealing the upstream effect of ROS in our system.ConclusionIn summary, MgO NPs may exhibit strong plasma distribution and mediate apoptosis by ROS induction in the cancer cell lines. These data demonstrate a safe aspect of MgO NPs on the proteins and normal cells and their application as a distinctive therapeutic approach in the cancer treatment.

“…It is considered that electrode materials with large surfacea reas and porous are highly critical for electrochemical performances. [53][54][55][56][57][58] Therefore, it is reasonable to assume that the hybrid porous hollow polyhedrons electrodes materials at scanning rates rangingf rom 5.0 to 100 mV s À1 .Apair of redox peaks appeared between the workingw indows 0-0.55 V, suggesting at ypical pseudocapacitive feature of hybrid porousC o 3 O 4 -CeO 2 materials.

“…Additionally, due to the reversible redox reaction, the stability of pseudocapacitors deteriorates during the cycling process [20,21]. CPs and transition metal oxides/hydroxides (Figure 3) are the typical candidates for the pseudocapacitor [22][23][24]. In contrast to EDLC, a pseudocapacitor builds up charges via fast and reversible surface faradaic reaction and electrosorption between electrolyte and electrode active materials at the appropriate potential window (rarely exceeding 1 V) [13,14].…”

Development of well-designed electrodes is the key to achieve high performance supercapacitors. Therefore, as one of the effective methods, a layer-by-layer (LBL) approach is often fruitfully employed for the fabrication of electrode material. Benefiting from a tunable parameter of the LBL approach, this approach has paved a way to design a highly ordered nanostructured electrode material with excellent performance. Conducting polymers (CPs) are the frontrunners in supercapacitors and notably, the LBL assembly of CPs is attracting extensive attention. Therefore, this critical review covers a comprehensive discussion on the research progress of CP-based composites with special importance on the LBL approach predominately for supercapacitors. Following a brief discussion on supercapacitors and CPs, the most up-to-date techniques used in LBL are highlighted.
