研究室紹介
Professor Taehee Kim's research lab specializes in advanced materials and biomedical engineering, focusing on the development of functional nanomaterials for energy and healthcare applications. Key research directions include designing smart nanomaterials such as memristors and block copolymer nanostructures for next-generation electronics, and engineering stem cells and non-viral gene delivery systems—particularly using mannosylated chitosan—for targeted immunotherapy and regenerative medicine. The lab also applies computational optimization techniques to solve complex engineering design problems, integrating materials science, nanotechnology, and biomedical engineering to address challenges in disease treatment and device performance.

15Recently a memristor ( Chua, L. O. IEEE Trans. Circuit Theory 1971 , 18 , 507 ), the fourth fundamental passive circuit element, has been demonstrated as thin film device operations ( Strukov, D. B.; Snider, G. S.; Stewart, D. R.; Williams, R. S. Nature (London) 2008 , 453 , 80 ; Yang, J. J.; Pickett. M. D.; Li, X.; Ohlberg, D. A. A.; Stewart, D. R.; Williams, R. S. Nat. Nanotechnol. 2008 , 3 , 429 ). A new addition to the memristor family can be nanoparticle assemblies consisting of an infinite
Cancer immunotherapy relies on the ability of the immune system to destroy tumor cells selectively and to elicit a long-lasting memory of such activity. Interleukin-12 (IL-12) is an immunomodulatory cytokine produced primarily by antigen-presenting cells, which play an important role in promoting Th1-type immune response and cell-mediated immunity. To augment the antitumor immune action by in vivo IL-12 gene delivery, mannosylated chitosan (MC) was prepared to induce mannose receptor-mediated en
Dendritic cells (DCs) are professional antigen presenting cells that induce, sustain, and regulate immune responses. Gene modification of DCs is of particular interest for immunotherapy of diseases where the immunes system has failed or is abnormally regulated, such as in cancer or autoimmune disease. Gene transfer using non-viral vectors is a promising approach for the safe delivery of therapeutic DNA. Among various non-viral vectors, chitosan is considered to be a good candidate for gene deliv
Engineering optimization problems usually contain various constraints and mixed integer-discrete-continuous type of design variables. This article proposes an efficient particle swarm optimization (PSO) algorithm for such problems. First, the constrained optimization problem is transformed into an unconstrained problem without introducing any problem-dependent or user-defined parameters such as penalty factors or Lagrange multipliers, though such parameters are usually required in general optimi
A hierarchical nanostructure of PS-b-PEO is demonstrated (see figure) with a novel approach by solvent vapor annealing of a micropatterned block copolymer thin film selectively spun cast on microcontact printed surface of SAMs. Dewetting of the thin film, inevitable during the ordering of block copolymer microdomains upon solvent annealing, is strictly confined to the patterned regions, leading to the controlled micropatttern with nearly perfect ordering of PEO microdomains.
Placenta-derived mesenchymal stem cells (PD-MSCs) have numerous advantages over other adult MSCs that make them an attractive cell source for regenerative medicine. Here, we demonstrate the therapeutic effect of PD-MSCs in ovariectomized (Ovx) rats and compare their efficacy when generated via a conventional monolayer culture system (2D, naïve) and a spheroid culture system (3D, spheroid). PD-MSC transplantation significantly increased the estradiol level in Ovx rats compared with the non-transp
