“…Hyperthermia and thermoablation is a procedure that is used to deliver localized heat energy for the destruction of an undesirable cell such as tumor. Hyperthermia requires controlled heating for long terms at temperatures ranging from 41-46°C for targeted cell disruption [75]. While thermoablation involves the temperature exceeding up to 50°C till cell death, the most favorable methods for wireless delivery of heat energy are by: i) using ultrasonic resonating mechanical structures and ii) using high-frequency magnetic elds [66, 72, 74].…”

Microrobots are motile microsystems constructed using physical, chemical and biological components for operations with respect to de nite application. In the present review, we have discussed the various aspects of bio-microrobots, their history and design. While designing a microrobot, two important parameters (and their varities)-actuation and sensing affect the different micromanipulation techniques to be employed (Magnetic, Optical, Electric, uidic or acoustic). The controlling and actuation system (Vision-based or Force-sensing) selected for the speci c application can dictate the fabrication type to be used for manufacture of the microrobot to be used. The controlling parameters are further in uenced by the type of propulsion systems, Powering system, and mobility in complex environment and applicability of the microrobot. Presently, the microrobotics has applications in biomedical and environmental engineering. In this review, we have analyzed various aspects of bio-microrobot design, fabrication and applications which can help the future works in nanosciences and bio-based microrobotics.

“…In recent years, a particular interest is attracted to biogenic magnetic nanoparticles. Since “bacteria with motility directed by the local geomagnetic field have been observed in marine sediments” by Richard Blakemore in 1975 [ 12 ], a large number of studies have been carried out in order to determine the properties of such particles, or, so-called magnetosomes, which are the intracytoplasmic membrane vesicles, containing magnetic nanocrystal covered in a lipid bilayer with proteins [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. The most important applications of such biogenic nanoparticles include the biosensors for medical diagnostics, and cancer diagnostics, in particular, vehicles for target delivery of anticancer agents [ 21 ], hyperthermia treatment employing alternating electromagnetic field [ 22 ], and tumor diagnostics using magnetic resonance imaging (MRI) [ 23 ].…”

Magnetic nanocarriers have attracted attention in translational oncology due to their ability to be employed both for tumor diagnostics and therapy. This review summarizes data on applications of synthetic and biogenic magnetic nanoparticles (MNPs) in oncological theranostics and related areas. The basics of both types of MNPs including synthesis approaches, structure, and physicochemical properties are discussed. The properties of synthetic MNPs and biogenic MNPs are compared with regard to their antitumor therapeutic efficiency, diagnostic potential, biocompatibility, and cellular toxicity. The comparative analysis demonstrates that both synthetic and biogenic MNPs could be efficiently used for cancer theranostics, including biosensorics and drug delivery. At the same time, reduced toxicity of biogenic particles was noted, which makes them advantageous for in vivo applications, such as drug delivery, or MRI imaging of tumors. Adaptability to surface modification based on natural biochemical processes is also noted, as well as good compatibility with tumor cells and proliferation in them. Advances in the bionanotechnology field should lead to the implementation of MNPs in clinical trials.
