Micro/Nanomotors for Water Purification

Chemistry - A European Journal, Год журнала: 2018, Номер 25(1), С. 106 - 121

Опубликована: Окт. 11, 2018

Self-propelled micro/nanomotors are synthetic machines that can convert different sources of energy into motion; at the same time, they able to serve innovative environmental applications, for example, water purification. The self-propelled micro and nanomachines rapidly zoom through solution, carrying catalytic surface or chemical remove degrade pollutants in a much faster fashion than static systems, which depend on diffusion fluxes. This review highlights recent progress pollutant detection removal applications.

Ultrafast Electrochemical Trigger Drug Delivery Mechanism for Nanographene Micromachines

Advanced Functional Materials, Год журнала: 2018, Номер 29(4)

Опубликована: Дек. 2, 2018

Abstract Nano/micromachines with autonomous motion are the frontier of nanotechnology and nanomaterial research. These self‐propelled nano/micromachines convert chemical energy obtained from their surroundings to propulsion. They have shown great potential in diagnostic therapeutic applications. This work introduces a high‐speed tubular electrically conductive micromachine based on reduced nanographene oxide (n‐rGO) as platform for drug delivery platinum (Pt) catalytic inner layer. n‐rGO/Pt micromachines loaded doxorubicin (DOX) by simple physical adsorption very high loading efficiency, displaying single‐ or multistrand wrapping DOX monomers cylinders. More importantly, it is found that electron injection into DOX@n‐rGO/Pt via electrochemistry leads expulsion within only few seconds. An vitro study confirms this efficient release mechanism presence cancerous cells. The unique properties micromotor enable effective management at tumor site thus enhances efficiency reduces side toxicity toward healthy tissue. carriers combine capacity conventional carbon‐based fast electrochemical drug‐release mechanism.

During the last two decades, engineering motion with small-scale matter has received much attention in several areas of research, ranging from supramolecular chemistry and colloidal science to robotics automation. The numerous discoveries innovative concepts realized motile micro- nanostructures have converged field swimmers. These man-made nanomachines can move fluids by transforming different forms energy mechanical motion. Recently, metal-organic frameworks (MOFs), which are crystalline coordination polymers high porosity, been proposed as key building blocks swimmer designs. materials possess required features for nanodevices, such cargo-loading capacity, biodegradability, biocompatibility, stimuli-responsiveness. In this review, we take a journey through major breakthroughs milestones area MOF-based First, brief introduction swimmers is provided. Next, review strategies that reported imparting MOFs. Finally, emphasize incorporation molecular machines into MOF's architecture means create highly integrated developments explored pave way toward use MOFs variety applications fields biomedicine, environmental remediation, on-the-fly chemistry.
