Abstract Injecting micro/nanorobots into the body to kill tumors is one of ultimate ambitions for medical nanotechnology. However, injecting current based on 3D‐printed biocompatible materials directly blood vessels targeted therapy often difficult, and mistakes in targeting can cause serious side effects, such as clots, oxidative stress, or inflammation. The natural affinity macrophages tumors, their phagocytosis ability invade make them outstanding drug delivery vehicles tumor therapy....
Abstract Border‐nearing microrobots with self‐propelling and navigating capabilities have promising applications in micromanipulation bioengineering, because they can stimulate the surrounding fluid flow for object transportation. However, ensuring biosafety of is a concurrent challenge bioengineering applications. Here, macrophage template‐based (cell robots) that be controlled individually or chain‐like swarms are proposed, which transport various objects. The cell robots constructed using...
The capability to precisely rotate cells and other micrometer-sized biological samples is invaluable in biomedicine, bioengineering, biophysics. We propose herein a novel on-chip cell rotation method using acoustic microstreaming generated by oscillating asymmetrical microstructures. When the vibration applied microchip with our custom-designed microstructures, two different modes of highly localized microvortices are that utilized achieve in-plane out-of-plane rotational manipulation...
Flexible magnetic small‐scale robots (overall dimensions smaller than 1 cm) can use a patterned magnetization profile to noninvasively access confined, enclosed liquid environment and therefore achieve applications in object manipulation or minimally invasive procedures. Existing magnetic‐controlled have shown wide usage for their high mobility higher degrees of freedom rigid counterparts. Herein, an octopus‐like soft robot is proposed potential biomedical engineering fields. First, control...
This paper presents a semi-automatic actuation system which can achieve bio-particles tracking, transportation, and high-precision motion control of robots in microfluidic chip. is mainly applied magnetically driven robots. An innovative manta ray-like robot was designed to increase stability non-contaminated manipulation environment. A multilayer piezo actuator generate high-frequency vibration decrease the friction between glass substrate. We also set up user-friendly GUI (Graphical User...
Magnetically Actuated Millirobots In article number 1900148, Lin Feng and co-workers present an octopus-like soft robot which can move freely in 3D workspace without constraints. A magnetic control system using the minimum of coils, is inspired by regular tetrahedron structure, designed to propel robot.
Magnetic microrobots can be propelled precisely and wirelessly in vivo using magnetic field for targeted drug delivery early detection. They are promising clinical trials since fields capable of penetrating most materials with minimal interaction, nearly harmless to human beings. However, challenges like the biocompatibility, biodegradation therapeutic effects these robots must resolved before this technique is allowed preclinical development. In study, we proposed a cell-robot based on...
Cell microrobot is now a hot topic in medical for cell therapeutics and disease therapeutics. Cells can delivery various payloads curation as vectors. However, the current problem low efficiency of controlling cells to target tissue, which greatly limits clinical applications microrobot. Therefore, it important find method improve movement at fixed point. Magnetic nanoparticle-labeled stem have become mature safe technology, so use external magnetic field targeting control robot...
The multiple degrees of freedom motion micro-nano robots in three-dimensional space(3D) using magnetic field, has promising applications biomedical ranging from drug delivery to cancer treatment with zero harm human body. This paper presented a newly established system consist four electromagnetic coils inspired by the regular tetrahedron structure and cell-robot is proposed for first time world. With minimum number coils, interference between electromagnets can be effectively avoided while...
