“…This property has been well-documented for glass and UF-Au by atomic force microscopy (AFM) with root-mean-square roughness values of 0.245 nm and 0.2-0.3 nm respectively. 33,34 Stine and colleagues have extensively characterized np-Au monoliths 8 which have a greater degree and variability of surface roughness (30-40 nm, data not shown). Furthermore, they have demonstrated that np-Au monoliths are open-ended mesoporous materials by (1) AFM characterization of the np-Au exterior and interior continuous porous structure, 8 (2) successful immobilization of proteins within the np-Au structure using a flow-through approach, 35 and (3) quantification of the surface area and pore volume of np-Au using nitrogen adsorption/desorption isotherms and Brunauer, Emmett, and Teller (BET) and Barrett-Joyner-Halenda (BJH) analysis.…”

“…Of these methods, flow alignment has shown the greatest promise for generating polar‐aligned arrays of MTs. For example, lithographic patterns along with electrical or fluid flow were used to pin and orient AFs on a surface, which in turn supported the directed transport of myosin coated beads in the natural geometry . Recently, analytical models were developed to optimize the formation of flow‐oriented MT arrays.…”

Here, the degree of MT alignment was shown to be limited by thermal forces, whereas the kinetics of the process was regulated by factors including the flow strength, MT stiffness, MT velocity, and tip length.…”

Biomolecular motors are a unique class of intracellular proteins that are fundamental to a considerable number of physiological functions such as DNA replication, organelle trafficking, and cell division. The efficient transformation of chemical energy into useful work by these proteins provides strong motivation for their utilization as nanoscale actuators in ex vivo, meso- and macro-scale hybrid systems. Biomolecular motors involved in cytoskeletal transport are quite attractive models within this context due to their ability to direct the transport of nano-/micro-scale objects at rates significantly greater than diffusion, and in the absence of bulk fluid flow. As in living organisms, biomolecular motors involved in cytoskeletal transport (i.e., kinesin, dynein, and myosin) function outside of their native environment to dissipatively self-assemble biological, biomimetic, and hybrid nanostructures that exhibit nonequilibrium behaviors such as self-healing. These systems also provide nanofluidic transport function in hybrid nanodevices where target analytes are actively captured, sorted, and transported for autonomous sensing and analytical applications. Moving forward, the implementation of biomolecular motors will continue to enable a wide range of unique functionalities that are presently limited to living systems, and support the development of nanoscale systems for addressing critical engineering challenges.

“…90 Wei et al developed a controlled method for the elaboration of F-actin track system which could be applied for nanodevices based on myosin motors. 172 By lithographic techniques, tracks restricting the movement direction of kinesin have been developed and investigations using Ca 2+ as movement regulator have also been promising. [173][174][175] An example of ATP synthases is F o F 1 -ATPase.…”

For several thousand millions of years nature has been crafting extremely intricate systems at nanoscale. With current technologies our range of action has passed from merely mimicking nature to redesign it. This work presents a novel perspective of the convergence of two young and promising fields: bionanotechnology (bionano) and synthetic biology (synbio). We explore the major advances made by the fusion of these fields in several areas including amino and nucleic acid based nanostructures. In this regard, we briefly discuss their application in gene regulation mechanisms (such as engineered riboswitches), self-assembly structures (taking advantage of bacterial S-layer, viral proteins and DNA origami), biological nanopores (whose properties can used as sensors, nucleic acid sequencers, nutrient intake and secretion devices, etc.) and molecular motors (allowing translocation of materials or movement of the entire system). Furthermore, the design of novel synthetic biopolymers (RNA, DNA and proteins), minimal cell approaches and cell-free systems technologies are also discussed under the perception of synbio/bionano. This led to the possibility of designing advanced engineered systems (micro/nano-biomachines) with desired feaapplications of this technology we also should be aware of ethical problems that may arise.
