Abstract:: ... In situ formation of a Cu-(m-phenylenediamine) (Cu-mPD) oligomer complex from copper chloride during the interfacial polymerization process was successfully employed to produce modified thin-film composite reverse osmosis membranes (TFC-RO) with antibiofouling properties. Membranes were characterized by field emission scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), X- ...

Abstract:: ... Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. Gene therapy utilizes gene delivery to deliver genetic material with the goal of treating a disease or condition in the cell. Actual viral vectors may have side effects, while actual systems using metal nanoparticles for gene delivery are toxic. Therefore, we designed here a biocompatible tri ...

Abstract:: ... Here, effect of solution pH on precipitation of silver decorated hydroxyapatite (Ag-HAp) nano powder during its wet-synthesis was systematically studied. XRD pattern of Ag-HAp nano powder synthesised at pH ranging from 5 to 10 shows that calcium hydrogen phosphate was formed as dominating phase when the solution pH was between 5 and 9 and this phase was gradually transformed into a stable HAp abov ...

Abstract:: ... Extracellular polymeric substances (EPSs) dispersed in natural waters play a significant role in relieving impacts to microbial survival associated with heavy metal release, yet little is known about the association of freely dissolved EPS ecosystem services with metal transformation in natural waters. Here, we demonstrate that dispersive EPSs mitigate the metal toxicity to microbial cells through ...
