“…Several 3D-printed bioreactors have demonstrated great potential in water treatment applications that were difficult to be achieved by conventional wastewater treatment systems. Cylindrical microrobots printed by SLA conveyed excellent water purification capability and great biocompatibility with mammalian cells[ 26 ]. Other intricate 3D-printed bioreactor designs, including fullerene-shaped bio-carriers[ 21 ] and gyroid-shaped carrier[ 63 ], have been shown to stimulate microbial assemblages for improved organic matter removal and better performance of biofilm reactors.…”

“…These direct cell printing techniques will not be discussed in this review. Another widely used 3D-printed method is the vat photopolymerization, including SLA and DLP, which prints by curing photosensitive resins with ultraviolet light[ 17 , 26 ]. SLA uses a laser beam that scans line-by-line to cure the photosensitive resin, whereas DLP uses a digital light projector to cure each layer of photoreactive resin in one go.…”

In recent years, three-dimensional (3D) printing has markedly enhanced the functionality of bioreactors by offering the capability of manufacturing intricate architectures, which changes the way of conducting in vitro biomodeling and bioanalysis. As 3D-printing technologies become increasingly mature, the architecture of 3D-printed bioreactors can be tailored to specific applications using different printing approaches to create an optimal environment for bioreactions. Multiple functional components have been combined into a single bioreactor fabricated by 3D-printing, and this fully functional integrated bioreactor outperforms traditional methods. Notably, several 3D-printed bioreactors systems have demonstrated improved performance in tissue engineering and drug screening due to their 3D cell culture microenvironment with precise spatial control and biological compatibility. Moreover, many microbial bioreactors have also been proposed to address the problems concerning pathogen detection, biofouling, and diagnosis of infectious diseases. This review offers a reasonably comprehensive review of 3D-printed bioreactors for in vitro biological applications. We compare the functions of bioreactors fabricated by various 3D-printing modalities and highlight the benefit of 3D-printed bioreactors compared to traditional methods.

“…AGNETIC field-driven manipulation of miniaturized robotic agents has attracted great research attention with a wide range of applications. Impressive results have been achieved during the last two decades ranging from contactless ocular surgery [1], targeted drug delivery [2]- [4], in-vitro diagnosis [5], endoscopy [6], minimally invasive surgery [7], and environmental remediation [8], [9] to name a few. Magnetic fields have been widely used in robotic micromanipulation due to their transparency to human and animal tissues, and their capacity to wirelessly address micro-objects.…”

Manipulation of small-scale matter is a fundamental topic in micro-and nanorobotics. Numerous magnetic robotic systems have been developed for the manipulation of microparticles in an ambient environment, liquid as well as on the air-liquid interface. These systems move intrinsically magnetic or magnetically tagged objects by inducing a magnetic torque or force. However, most of the materials found in nature are nonmagnetic. Here, we report a ferrofluidic manipulator for automatic two-dimensional manipulation of non-magnetic objects floating on top of a ferrofluid. The manipulation system employs eight centimeter-scale solenoids, which can move non-magnetic particles by deforming the air-ferrofluid interface. Using linear programming, we can control the motion of the non-magnetic particles with a predefined trajectory of a line, square, and circle with a precision of 25.1±19.5 µm, 34.4±28.4 µm and 33.4±26.6 µm, respectively. The ferrofluidic manipulator is versatile with the materials and the shapes of the objects under manipulation. We have successfully manipulated particles made of polyethylene, polystyrene, a silicon chip, and poppy and sesame seeds. This work shows a promising venue for the manipulation of living and nonliving matter at the air-liquid interface.

“…Combining with titanium could drastically increase the damage tolerance of the ceramic and also provide added application specific functions. For example, a device of combined TiO 2 /Ag and Cu/CoNiP was shown to effectively perform as magnetically rolling microrobots for water purification [13].…”

In present work, the combination of spark plasma sintering (SPS) and selective laser melting (SLM) techniques was introduced to produce composite materials where silver-doped titania (TiO 2 ) ceramics were reinforced with ordered lattice structures of titanium alloy Ti6Al4V. The objective was to create bulk materials with an ordered hierarchical design that were expected to exhibit improved mechanical properties along with an antibacterial effect. The prepared composite materials were evaluated for structural integrity and mechanical properties as well as for antibacterial activity towards Escherichia coli. The developed titanium-silver/titania hybrids showed increased damage tolerance and ultimate strength when compared to ceramics without metal reinforcement. However, compared with titania/silver ceramics alone that exhibited significant antibacterial effect, titanium-reinforced ceramics showed significantly reduced antibacterial effect. Thus, to obtain antibacterial materials with increased strength, the composition of metal should either be modified, or covered with antibacterial ceramics. Our results indicated that the used method is a feasible route for adding ceramic reinforcement to 3D printed metal alloys.
