“…Thanks to its high selectivity and controllability, DEP is applied in particle (solid and liquid) enrichment and classification as well as intensification of conventional separation technologies such as demulsification and membrane filtration. DEP was also used for assembly of nanostructures, which has already been elaborately reviewed [93][94][95][96] and therefore will not be discussed here. A summary of all discussed applications can be found in the Supporting Information, Table S4.…”

A review of dielectrophoretic separation and classification of non-biological particles Dielectrophoresis (DEP) is a selective electrokinetic particle manipulation technology that is applied for almost 100 years and currently finds most applications in biomedical research using microfluidic devices operating at moderate to low throughput. This paper reviews DEP separators capable of high-throughput operation and research addressing separation and analysis of non-biological particle systems. Apart from discussing particle polarization mechanisms, this review summarizes the early applications of DEP for dielectric sorting of minerals and lists contemporary applications in solid/liquid, liquid/liquid, and solid/air separation, for example, DEP filtration or airborne fiber length classification; the review also summarizes developments in DEP fouling suppression, gives a brief overview of electrocoalescence and addresses current problems in high-throughput DEP separation. We aim to provide inspiration for DEP application schemes outside of the biomedical sector, for example, for the recovery of precious metal from scrap or for extraction of metal from low-grade ore.

“…RF processes are also high resolution but not suitable as standalone processes for creating tissue constructs, similar to SM processes. RF processes utilizing electrical (Boccaccini et al, 2010; Liu et al, 2019), optical, and magnetic fields (Armstrong & Stevens, 2020; Lim et al, 2011) enable manipulation of nanoparticles, while the ones employing acoustic fields are more suitable for manipulation of microparticles due to the size constraints associated with the viscous penetration depth (Drinkwater, 2016). Notably, low‐intensity ultrasound has been used toward cell functionalization, including aiding differentiation (Aliabouzar, Lee, Zhou, Zhang, & Sarkar, 2018; Osborn et al, 2019), proliferation (Subramanian et al, 2013) and ECM production (Min, Choi, & Park, 2007).…”

Recapitulation of multiscale structure–function properties of cells, cell‐secreted extracellular matrix, and 3D architecture of natural tissues is central to engineering biomimetic tissue substitutes. Toward achieving biomimicry, a variety of biofabrication processes have been developed, which can be broadly classified into five categories—fiber and fabric formation, additive manufacturing, surface modification, remote fields, and other notable processes—each with specific advantages and limitations. The majority of biofabrication literature has focused on using a single process at a time, which often limits the range of tissues that could be created with relevant features that span nano to macro scales. With multiscale biomimicry as the goal, development of hybrid biofabrication strategies that synergistically unite two or more processes to complement each other's strengths and limitations has been steadily increasing. This work discusses recent literature in this domain and attempts to equip the reader with the understanding of selecting appropriate processes that can harmonize toward creating engineered tissues with appropriate multiscale structure–function properties. Opportunities related to various hybridization schemes and a future outlook on scale‐up biofabrication have also been discussed.

“…Quake et al [50] reported a large-scale integrated microfluidic device in 2002. Briefly, microfluidic chip is a miniature biochemical analysis instrument that integrates the experiment steps of biochemical sample pretreatment [51], particle manipulation [52], biochemical reaction [53], detection and result analysis [54] into a device in a scale of tens to hundreds of microns, without sacrificing their performance. Micro biochemical analysis units and systems are built on the microfluidic chips by micronano processing technology, enabling rapid detection and analysis of biochemical samples such as organics, inorganics, proteins, and nucleic acids.…”

Neutrophil chemotaxis plays a vital role in human immune system. Compared with traditional cell migration assays, the emergence of microfluidics provides a new research platform of cell chemotaxis study due to the advantages of visualization, precise control of chemical gradient, and small consumption of reagents. A series of microfluidic devices have been fabricated to study the behavior of neutrophils exposed on controlled, stable, and complex profiles of chemical concentration gradients. In addition, microfluidic technology offers a promising way to integrate the other functions, such as cell culture, separation and analysis into a single chip. Therefore, an overview of recent developments in microfluidic-based neutrophil chemotaxis studies is presented. Meanwhile, the strength and drawbacks of these devices are compared.
