    　View Summary

    Hydrogels are emerging as enabling materials for a wide range of new applications for soft robots because of their flexibility. Some of the polymer chains that make up the hydrogel have a nano-scale function of swelling and contracting in response to external stimuli. In addition, because the network of polymer chains is on the nanometer order, it is possible to encapsulate various functional materials. Therefore, stimulus-responsive hydrogels and functional materials encapsulating hydrogels are also being actively studied for use as soft robot components. From a fundamentals point of view, the nano-scale functions of hydrogels, fabrication method, and integration with functional materials must be considered for each specific application. This section provides a basic understanding of hydrogels and the recent development of novel fabrication and integration of hydrogel with functional materials such as magnetic nanoparticles, Pt catalyst, graphene, photonic colloidal crystal, and living cells.

  • Adeno-Associated Virus-Encapsulated Alginate Microspheres Loaded in Collagen Gel Carriers for Localized Gene Transfer

    Kurashina Y., Kurihara S., Kubota T., Takatsuka S., Hirabayashi M., Shimmura H., Miyahara H., Hioki A., Matsushita Y., Muramatsu J., Ogawa Y., Fujioka M., Okano H.J., Onoe H.

    Advanced Healthcare Materials (Advanced Healthcare Materials)  13 ( 12 )  2024.05

    ISSN  21922640

    　View Summary

    This work reports localized in vivo gene transfer by biodegradation of the adeno-associated virus-encapsulating alginate microspheres (AAV-AMs) loaded in collagen gel carriers. AAV-AMs are centrifugally synthesized by ejecting a mixed pre-gel solution of alginate and AAV to CaCl2 solution to form an ionically cross-linked hydrogel microsphere immediately. The AAV-AMs are able to preserve the AAV without diffusing out even after spreading them on the cells, and the AAV is released and transfected by the degradation of the alginate microsphere. In addition, AAV-AMs can be stored by cryopreservation until use. By implanting this highly convenient AAV-encapsulated hydrogel, AAV-AMs can be loaded into collagen gel carriers to fix the position of the implanted AAV-AMs and achieve localized gene transfer in vivo. In vivo experiments show that the AAV-AMs loaded in collagen gel carriers are demonstrated to release the encapsulated AAV for gene transfer in the buttocks muscles of mice. While conventional injections caused gene transfer to the entire surrounding tissue, the biodegradation of AAV-AMs shows that gene transfer is achieved locally to the muscles. This means that the proposed AAV-loaded system is shown to be a superior method for selective gene transfer.

  • Light-Triggered Transmittance Control in Thermoresponsive Hydrogels by Femtosecond Laser Direct Writing

    Kashikawa K., Tomikawa H., Onoe H., Terakawa M.

    ACS Applied Optical Materials (ACS Applied Optical Materials)  2 ( 4 ) 565 - 573 2024.04

    　View Summary

    Thermoresponsive hydrogels, which exhibit changes in their optical properties and volume due to temperature variations, are promising candidates for applications in soft devices. In this study, we demonstrate the modulation of transmittance in a thermoresponsive hydrogel through light stimulation employing gold microstructures fabricated via multiphoton photoreduction. The spatial integration of photoresponsiveness, attributed to high-density gold nanoparticles within the thermoresponsive hydrogel, was accomplished through the high-speed laser scanning of femtosecond laser pulses. The temperature measurement during the fabrication of the gold microstructure revealed that the high-speed and multiple scanning over the same path effectively reduced the temperature in the irradiated area of femtosecond laser pulses. The present approach enabled the mitigation of thermal effects during the fabrication, resulting in minimizing distortion in the fine lines of the structures. Upon exposure to stimulus light, a rapid change in the transmittance of the region where the structures were fabricated was prominently observed. The present method unveils a promising avenue for the advancement of light-responsive soft devices.

  • In-line micro-spectrometer with a structural color polymer filter for the color and concentration monitoring system

    Nishita S., Onoe H.

    Sensors and Actuators A: Physical (Sensors and Actuators A: Physical)  367 2024.03

    ISSN  09244247

    　View Summary

    Monitoring systems for color and concentration of liquids have an important role in improving the fabrication process stably, not only in pipelines but also in microchannels. Our suggested in-line micro-spectrometer with an elastic structural color filter has detectability for color and concentration changes with a 40-mm size. The sequence of our device is the following: (1) the elastic structural color filter splits the white light from an LED, (2) the split light transmits the sample liquid, and (3) a photodiode receives the transmitted light. The structural color polymer is mechanically compressed inside the micro-spectrometer, leading to fixing the optical path even though the light wavelength is changed continuously. We fabricated the elastic structural color polymer with 200 nm silica nanoparticles and PEGPEA (poly- (ethylene glycol) phenyl ether acrylate). The prototype of the in-line micro-spectrometer with a red (λ = 596 nm) filter showed the detectability of the difference between yellow and green dyes. Moreover, the micro-spectrometer successfully distinguished the concentration of green-dyed water. This proposed in-line micro-spectrometer would contribute to developing in-line microfluidic color monitoring systems for biochemical analyses and material production.

  • Mucin-Layer-Secreting in Vitro Intestinal Tube-Shaped Device with Cryptic Structure for Bacterial Co-Culture

    Uramoto S., Tanaka S., Itai S., Onoe H.

    Proceedings of the IEEE International Conference on Micro Electro Mechanical Systems (MEMS) (Proceedings of the IEEE International Conference on Micro Electro Mechanical Systems (MEMS))     485 - 488 2024

    ISSN  10846999

    　View Summary

    We propose an in vitro intestinal tube-shaped device with a secreted mucin layer that enables us to achieve stable and continuous co-culturing with bacteria. Our tube-shaped device is made of collagen hydrogel and has 3D crypt-like structures created by electrolytically generated microbubbles. Bacterial suspension can be perfused via glass/silicone tubes attached at both ends of the tube device. Supply of culture medium diffused from the outside of the tube ensures a stable culture of Caco-2 and HT29 cells on the inside of the tube. We confirmed that HT29 cells mainly secreted a mucin layer in the apical portion of cryptic structures that spatially separates the intestinal cells and bacteria as seen in vivo environments. As a result, the co-culture of intestinal cells and lactobacillus in vitro was demonstrated in the 3D crypt-like structures in our intestinal tube-shaped device.

  • Entirely Biodegradable Wireless pH Sensor with Split-Ring Resonators for Soil pH Monitoring

    Sakabe K., Kan T., Onoe H.

    Advanced Materials Technologies (Advanced Materials Technologies)   2024

    　View Summary

    This paper describes a wireless and battery-free soil pH sensor made entirely of degradable materials. Soil pH monitoring is significant for precision agriculture and environmental conservation because soil health can be estimated by measuring soil pH. Soil pH can be measured by collecting soil samples and analyzing them in a laboratory environment or by inserting an electrode-type sensor into the soil and measuring soil pH on site. However, neither method is suitable for wide-area soil pH sensing for precision agriculture or environmental conservation. Herein, a fully biodegradable wireless pH sensor is presented that can be dispersed to outdoor environment to detect soil acidity. The sensor is operated wirelessly through split-ring resonators (SRRs) that consist of patterned octacalcium phosphate (OCP)-coated magnesium (Mg) on a poly-lactic acid (PLA) sheet. At acidic soil pH, the degradation of each SRR results in a change in the electromagnetic response of the sensor. The operation of the sensor in six different types of acidic soils is demonstrated to distinguish the acidic soil wirelessly. It is expected that the biodegradable sensor can be applied to low-cost, easy-to-use, and environmentally friendly monitoring of soil pH.
