Smart materials designing and optimization for wearable bio-applications
I have been researched designing and fabrication optimizing for smart materials with diverse geometries and functionalities tailored for wearable bio-applications. My primary research interests lie in fabricating single polymer or biomaterial-based fibers, as well as creating functionalized composite fibers by blending two or more materials through electrospinning process. My focus has been on optimizing processes to enhance the functional efficiency of smart materials, thereby maximizing user-required functionalities.
Moreover, I have applied these versatile materials to various wearable healthcare applications, including multifunctional wound dressings (Adv. Funct. Mater., 2316196, 2024 & Adv. Mater. Technol., 8, 2201765, 2023), diagnostic garment for genetic diseases (Mater. Horiz., 10 (10), 4163, 2023), glucose sensing patches by SERS, and photodegradable bactericidal masks utilizing visible light irradiation (Adv. Funct. Mater., 2401404, 2024). I anticipate that these research endeavors will foster the ongoing advancement of the bio industry and contribute to enhancing human quality of life.
Antimicrobial composite with biomaterials
Antimicrobial properties play a crucial role in disease prevention among humans. I've been focused on the development of antimicrobial textiles and films derived from natural sources to enhance antimicrobial efficacy and ensure safety. For instance, substances rich in polyphenols like curcumin extracted from turmeric, and lignin derived from wood, exhibit potent antimicrobial properties without compromising safety (Adv. Mater. Technol., 8, 2201765, 2023 & Mater. Horiz., 10 (10), 4163, 2023). My efforts have centered on evaluating the biocompatibility and enhancing the antimicrobial efficacy of these composites for various bio-applications and food preservation.

Micro/nano structuring and compositing
I am also keenly interested in constructing hierarchical structures using materials at the nano/micro scale and advancing functional composite films. I have successfully fabricated diverse micro/nano-scale structures employing MEMS/NEMS processes and nanoimprinting techniques (Adv. Mater., 36, 2300871, 2024). Surface modification and etching were executed through oxygen and fluorine-based plasma treatments, obviating the necessity for separate adhesives. This breakthrough facilitated the transfer of various micro/nano patterns onto substrates like wafers, glass, electrospun fibers, and leaves for the first time (Nat. Commun., 14 (1), 833, 2023 & Adv. Funct. Mater., 2024), allowing us to imbue them with a range of functionalities tailored to user requirements, including superhydrophobic surfaces, formation of conductive networks, modification of optical properties, and energy storage.
