“…Finally, bio‐hybrid devices also have the potential to be used in environmental monitoring applications. Microorganisms are already being applied as sensors to detect agents such as salt, glucose, and heavy metal pollutants . Swarms of bio‐hybrid microswimmers could be deployed into a microenvironment, steered using external and cell‐based control methods, and be engaged to detect specific chemicals in a targeted region of interest.…”

As we move towards the miniaturization of devices to perform tasks at the nano and microscale, it has become increasingly important to develop new methods for actuation, sensing, and control. Over the past decade, bio-hybrid methods have been investigated as a promising new approach to overcome the challenges of scaling down robotic and other functional devices. These methods integrate biological cells with artificial components and therefore, can take advantage of the intrinsic actuation and sensing functionalities of biological cells. Here, the recent advancements in bio-hybrid actuation are reviewed, and the challenges associated with the design, fabrication, and control of bio-hybrid microsystems are discussed. As a case study, focus is put on the development of bacteria-driven microswimmers, which has been investigated as a targeted drug delivery carrier. Finally, a future outlook for the development of these systems is provided. The continued integration of biological and artificial components is envisioned to enable the performance of tasks at a smaller and smaller scale in the future, leading to the parallel and distributed operation of functional systems at the microscale.

“…In theory, the adsorption process can offer flexibility in design and operation and in many cases will produce high-quality treated effluent. In addition, as the adsorption is sometimes reversible and adsorbent can be regenerated by suitable desorption process, various types of adsorbents have found application in the removal of heavy metals, including activated carbon [2,3], carbon nanotubes [4][5][6], polymeric adsorbents [7], metal oxides [8], and bioadsorbents [9][10][11][12]. Among these adsorbents, iron-based magnetic nanomaterials have distinguished themselves by their unique properties, such as larger surface area-volume ratio, diminished consumption of chemicals, and no secondary pollutant.…”

This study investigated the applicability of maghemite (γ-Fe2O3) nanoparticles for the selective removal of toxic heavy metals from electroplating wastewater. The maghemite nanoparticles of 60 nm were synthesized using a coprecipitation method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDX). Batch experiments were carried out for the removal of Pb2+ions from aqueous solutions by maghemite nanoparticles. The effects of contact time, initial concentration of Pb2+ions, solution pH, and salinity on the amount of Pb2+removed were investigated. The adsorption process was found to be highly pH dependent, which made the nanoparticles selectively adsorb this metal from wastewater. The adsorption of Pb2+reached equilibrium rapidly within 15 min and the adsorption data were well fitted with the Langmuir isotherm.
