Manipulation and navigation of micro nanoswimmers in different fluid environments can be achieved by chemicals, external fields, or even motile cells. Many researchers have selected magnetic fields as the active actuation source based on advantageous features this strategy such remote spatiotemporal control, fuel-free, high degree reconfigurability, programmability, recyclability, versatility. This review introduces fundamental concepts advantages micro/nanorobots (termed here "MagRobots") well basic knowledge materials, setups for manipulation, field configurations, symmetry-breaking strategies effective movement. These are discussed to describe interactions between fields. Actuation mechanisms flagella-inspired MagRobots (i.e., corkscrew-like motion traveling-wave locomotion/ciliary stroke motion) surface walkers surface-assisted motion), applications other propulsion approaches, stimulation beyond provided followed fabrication techniques (quasi-)spherical, helical, flexible, wire-like, biohybrid MagRobots. Applications targeted drug/gene delivery, cell minimally invasive surgery, biopsy, biofilm disruption/eradication, imaging-guided delivery/therapy/surgery, pollution removal environmental remediation, (bio)sensing also reviewed. Finally, current challenges future perspectives development magnetically powered miniaturized motors discussed.

Chemically Fueled Self‐Assembly in Biology and Chemistry

Angewandte Chemie International Edition, Год журнала: 2021, Номер 60(37), С. 20120 - 20143

Life is a non-equilibrium state of matter maintained at the expense energy. Nature uses predominantly chemical energy stored in thermodynamically activated, but kinetically stable, molecules. These high-energy molecules are exploited for synthesis other biomolecules, activation biological machinery such as pumps and motors, maintenance structural order. Knowledge how transferred to biochemical processes essential development artificial systems with life-like processes. Here, we discuss can be used control organization organic Four different strategies have been identified according distinguishable physical-organic basis. For each class, one example from biology chemistry discussed detail illustrate practical implementation concept distinct opportunities they offer. Specific attention paid discussion chemically fueled self-assembly. We meaning self-assembly, its kinetic origin, develop synthetic systems.

Molecular Pumps and Motors

Pumps and motors are essential components of the world as we know it. From complex proteins that sustain our cells, to mechanical marvels power industries, much take for granted is only possible because pumps motors. Although molecular have supported life eons, it recently chemists made progress toward designing building artificial forms microscopic machinery present in nature. The advent machines has scientists an unprecedented level control over relative motion molecules through development kinetically controlled, away-from-thermodynamic equilibrium chemistry. We outline history motors, focusing specifically on innovations enable design synthesis central this Perspective. A key insight connecting biomolecular physical motions by which these carry out their function unambiguously at every instant. operation can be described trajectory thermodynamics, a theory based work Onsager, grounded firm foundation principle reversibility. Free energy derived from thermodynamically non-equilibrium reactions favors some reaction pathways others. By with kinetic asymmetry, one engineer potential landscapes harness external drive formation maintenance geometries component parts away-from-equilibrium, would impossible achieve standard synthetic approaches.
