This paper presents a study of microstructure formation in bioresorbable Fe-Mn-Si alloys for temporary implants under high-pressure torsion (HPT) at room temperature and at 300 °C. The effect of silicon on the mechanism of microstructure formation under HPT and, as a consequence, on the mechanical, corrosion and biological properties of the alloys is studied. It is established that Si promotes martensitic transformation. HPT leads to an increase in the microhardness values of the studied alloys from ~1560 MPa in the initial state to ~5500 MPa (160–560 HV) due to structure refinement and phase transformation. An increase in the electrochemical corrosion rate of Fe-Mn-Si alloys to ~0.5 mm/year is established due to grain refinement to nanosize and the formation of strain-induced martensite. In vitro cytotoxicity and induced hemolysis studies showed that Fe-Mn, Fe-Mn-3.7Si, and Fe-Mn-5Si alloys after annealing and HPT can be characterized as biocompatible.

Nearly 80 million people in the world deal with medical conditions that cause involuntary periodic movements known as tremors. Wearable soft robotic devices offer a potential solution for actively suppressing these tremors. However, existing prototypes face limitations in actuation performance and complex testing procedures. We present a comprehensive approach for the rapid evaluation of emerging wearable tremor-suppression technologies. This method combines reproducing patient-recorded tremor episodes and measuring tremor suppression in a robotic platform, termed a “mechanical patient”, with validation of the achieved suppression performance of soft actuators via biomechanical modeling, thereby avoiding time-consuming clinical testing in the early stages of development. Using this approach, we highlight that an antagonistic pair of slim and lightweight electrohydraulic actuators can effectively suppress clinically relevant tremors between 2 and 8 Hz. The biomechanical model confirms that the pair of actuators generates adequate suppression forces for all tested tremors.

In situ therapeutic agent production strategy is promising to overcome the drawbacks of direct drug delivery. Hypoxia provides a great target for precise treatment of tumor. Here we report a copper ion competition-based nanoparticle (NP) for hypoxia-activated formation of diethyldithiocarbamate (DTC)-copper complex, an immunogenic cell death (ICD) inducer. The NP is composed of an amphiphilic hypoxia-responsive DTC precursor and a fluorescence quenched copper ion-chelated squaric acid. In hypoxic tumor cells, the azobenzene linker in DTC precursor can be cleaved through bioreduction, leading to DTC release and subsequent copper ion exchange between DTC and squaric acid. Simultaneous formation of toxic DTC-copper complexes and fluorescence recovery will allow for visualization of in situ therapeutic agents production. Furthermore, the DTC-copper complexes can induce ICD and promote cytotoxic T lymphocyte infiltration for cancer immunotherapy. This study not only provides a promising hypoxia-activated nanomedicine for precision cancer therapy, but also a visualization strategy for evaluating the treatment process.

Recent advances in materials and flexible electronics for peripheral nerve interfaces

Bioelectronic Medicine 2018年第1期4卷 1页

Peripheral nerve interfaces are a central technology in advancing bioelectronic medicines because these medical devices can record and modulate the activity of nerves that innervate visceral organs. Peripheral nerve interfaces that use electrical signals for recording or stimulation have advanced our collective understanding of the peripheral nervous system. Furthermore, devices such as cuff electrodes and multielectrode arrays of various form factors have been implanted in the peripheral nervous system of humans in several therapeutic contexts. Substantive advances have been made using devices composed of off-the-shelf commodity materials. However, there is also a demand for improved device performance including extended chronic reliability, enhanced biocompatibility, and increased bandwidth for recording and stimulation. These aspirational goals manifest as much needed improvements in device performance including: increasing mechanical compliance (reducing Young’s modulus and increasing extensibility);improving the barrier properties of encapsulation materials;reducing impedance and increasing the charge injection capacity of electrode materials;and increasing the spatial resolution of multielectrode arrays. These proposed improvements require new materials and novel microfabrication strategies. This mini-review highlights selected recent advances in flexible electronics for peripheral nerve interfaces. The foci of this mini-review include novel materials for flexible and stretchable substrates, non-conventional microfabrication techniques, strategies for improved device packaging, and materials to improve signal transduction across the tissue-electrode interface. Taken together, this article highlights challenges and opportunities in materials science and processing to improve the performance of peripheral nerve interfaces and advance bioelectronic medicine. © 2018, The Author(s).
