A new type of cement (named 'nanocement') formulated with bioactive glass nanoparticles showed potential performance including angiogenic stimulation and osteoinductivity. The work was published in Biomaterials, 2018, 162, 183, by Kang MS et al.
A collaborative commercialization research institute, named GENTREN (GENoss + itREN) established with the supportive fund (500M/y up to 2 years) from NRF.
Gentren started to develop and commercialize dental synthetic bone graft materials and other root canal filling materials.
Our research and technologies initiated to become reality to the market throughout this project.
This was motivated by the transfer of two intellectural properties of Prof. Kim HW to biomaterials company (Genoss) with 100M won and 3% royalty
ITREN expanded its International cooperation with Peking University Shenzhen Graduate School in Dec, 2017.
ITREN has recently started collaborative works with Pf. hou Qiang and Li Shu-peng about utilization of therapeutic nanoparticles for treating neuronal diseases. Impactful research will be expected from these collaborative works.
Bioactive multi-functional nanoparticles developed to treat and repair infected pulpal tissue through the delivery of silver ion and antibiotics. This work was published in Biomaterials, 2017, 142, 62 (Drug/ion co-delivery multi-functional nanocarrier to regenerate infected tissue defect).
Prof. Lee HH developed glass ionomer cement with improved mechanical properties and mineralization with the help of bioactive nanoparticles, highlighting the potential for dental caries treatment. This work was published in Dental Mater, 2017, 33(7), 805-817
Joint work led by Prof. Kim HW and Hyun JK reported the effective role of nanoceria optimally dosed to a contused spinal cord of rat in restoring the function. This work was published in Advanced Science, 2017, 8, 1700034, with the title ‘Functional Recovery of Contused Spinal Cord in Rat with the Injection of Optimal-Dosed Cerium Oxide Nanoparticles'.
A review article in Nano Today entitled ‘Extra- and intra-cellular fate of nanocarriers under dynamic interactions with biology’, provides insight into how the nanoparticles can journey along the biological barriers in extra and intracellular space with specific mechanisms, and how to design new nanoparticles for delivery purpose.
NRF grants successfully funded for:

Microspheres developed to release silicate ions demonstrated excellent angiogenic effects in vitro and in vivo, suggesting the potential implication of silicate ions in stimulating angiogenesis. Moreover, the silicate ions synergize with VEGF, evidenced by the co-delivery approach. This research was published in Biomaterials, by Dashnyam K et al.
