Core Technology

• Science@Home Inc. was established for commercializing patented technology on the research result of Professor Lee Yoon-sik, Chemical and Biological Engineering Department of Seoul National University, and  has the know-how for developing new bio-nanomaterials and effective screening system.
• As a subsidiary of Seoul National University Technology Holdings, it has established a research and development platform to industrialize related patent technologies.
• The core technology is to develop smart bio-materials based on self-assembled peptide, has also accumulated experience of the solid phase peptide synthesis and manufacturing peptides.

• Tyrosine residues are known to play an important function in resillin and gluten, an elastic protein that is often present in the legs of fleas and wing muscles of dragonflies.
• Cross-linking or covalent bonding of tyrosines in the proteins leads to a folding structure, which maintains the high level of protein intensity and storage modulus. This means that tyrosine-based peptide materials are biocompatible in the form of biogel

• YC7 PEPTIDE is one of tyrosine rich peptides that contain a lot of tyrosines, which is a self-assembly characteristic that creates a three-dimensional structure on its own due to intermolecular forces in the solution and can be formed by various structures such as nano-scale spherical, fibrous, and film structures according to conditions.

• In particular, the nano-film formed is strong enough to overcome the surface tension of the aqueous solution and forms a multilayered structure that can be stacked according to the peptide concentration in the solution (the thickness of the fault structure is about 1.4 nm, and the thickness varies according to the number of layers, and approximately 50-400 nm)

• Due to the non-cytotoxic and biocompatible properties, YC7 PEPTIDE can be applied to various bio-materials, especially used as a binding layer between heterogeneous biomaterials. It can be used for bio-materials such as elastic hydrogels, reactive drug delivery vesicles, floating scafolds for cell culture, ion selective membranes, and protein-mimic catalysts.

• Plants generally produce organic matter and energy needed for growth in chlorophyll through photosynthesis with sunlight

• In addition to plants, phototrophs grow by converting light energy into bioenergy in the form of microelectronic energy using natural pigments similar to chlorophyll in the body.

• It is a substance that is synthesized and excreted in the human body and is often present in the yellow stripes of honeybees and wasps

• David Bergman, a professor of physics at Tel Aviv University in Israel, confirms that a honeybee or wasp creates bio-energy through photosynthesis using the yellow stripes on the belly. (Ref. Naturwissenschaften, December 2010, Vol. 97, Iss. 12, pp 1067–1076)

• The reason honeybees can be active during the daytime when sunlight is strong even without feeding, is because they convert light energy into micro-electrical energy through photosynthetic natural pigments to produce bio-energy needed for the metabolism.

• Confirm that the stronger the sunlight, the greater the activity of the honeybees
• lBy producing the energy required through sunlight, continuously active for several miles

• Joaquim C. G. Esteves da Silva researchers (University of Porto) have identified the entire structure called Bioluminescence in the glowing process of firefly that the precursor of Luciferin oxidizes through the metabolic process of the Luciferase enzyme.

• This bio-light emiting process is a phenomenon in which living things emit light through chemical processes, and is highly efficient with a luminous efficiency of 40-90%. There is no heat generated unlike artificial lighting, so it is also called cold light.

• Recently the bio-lighting system using Luciferin has been used to identify light-sensitive cells or tissues in bio-imaging and to track specific gene expression in genetic engineering.

• Since the early 2000s, bio-lighting systems have been studied. Philips has developed home lighting using E. coli bacteria, and Glowee, a French company, has developed bio-lighting for front signs of the store and city road as the main market, but the maximum duration was as short as three days, which caused economic problems.

• The research of bio-luminescence process has been expanded to plants in addition to bacteria, insects and marine biomass. Genetic manipulation have been applied to some tobacco crops for bioluminescence, but the study was halted due to safety problems and difficulties in mass production caused by the transformation of genetic modification.
