본 발명은 세포의 지질막(cell membrane)에서 유래된 나노소포체(nanovesicles), 이의 제조방법, 상기 나노소포체를 이용한 약제학적 조성물, 및 진단 키트 등에 관한 것이다. 본 발명에 따른 세포 지질막 유래 나노소포체는 치료용 또는 진단용 물질 전달에 불필요한 세포 내 물질(유전 물질 및 세포 내 단백질)이 제거되어 잠재적 부작용을 없앨 수 있고, 세포 또는 조직 타겟팅이 가능하므로 목표한 세포 또는 조직에 주로 치료용 또는 진단용 물질을 전달하고 다른 곳에 치료용 또는 진단용 물질의 전달을 억제함으로써 약물 등 치료용 물질의 부작용을 줄여서 질병 치료 과정에서 환자의 고통과 불편을 줄일 수 있으며, 치료효능을 증가시킬 수 있다. 또한, 질병 치료용 또는 진단용 물질이 로딩된 본 발명의 세포 지질막 유래 나노소포체 및 그의 제조 방법은 in vitro 또는 in vivo 에서 치료 또는 진단용, 또는 실험용으로 사용될 수 있다.
摘要:
The present invention refers to a pharmaceutical formulation for injection comprising fluorescent nanoparticles as in vivo diagnostics. The present invention relates to an injectable pharmaceutical formulation for human medicine and/or veterinary use, comprising 17% to 20% per weight of poloxamer 407 and 3% - 15% per weight of poloxamer 188, 0.10 nM to 10.0 μΜ fluorescent nanoparticles and water or an aqueous buffer, wherein the pharmaceutical formulation is liquid at 4°C - 32°C and forms a gel at about 37°C, their use as an in vivo marker and methods of their preparation. The inventive formulation is useful for local control and prevention of spreading/diffusion of nanoparticles, and thus allows full utilization of their quantum physics properties for example as a tool to enable surgical precision of tumor removal; even without tumor specific epitope binding antibodies.

摘要:
The present invention relates to compounds that can be used link substrates to molecules, typically for biological applications such as imaging and the like. The compounds contain a cyclooctyne which is joined, via a linking group, to a moiety such as a squarate, amine, aminooxy, hydrazide, semicarbazide or carbohydrazide. The cyclooctyne moiety acts as the coupling partner to an azide-functionalised substrate or molecule, whilst the other moiety acts as the coupling partner to an amine-, aldehyde- or ketone-functionalised molecule or substrate. The invention therefore also relates to processes of synthesis of such compounds and further use of the compounds to link a substrate to a molecule.

摘要:
This invention is related to preparation of photosensitive ruthenium based aminoacid monomers and oligomers, aminoacid monomer-protein cross- linking using photo sensitat ion and conjugation on micro and nano-structures by ruthenium-chelate based monomers. Its vast range biotechnolgy applications of multifunctional, biocompatible, stabilE and specific micro and nanobio-conjugates, which will stand-alone or simultaneously enable (i) both purification and determination, (ii) both targeting and imaging and theranostics and (iii) catalysis and determination. The construction and method of preparation is applicable to silica materials, superparamagnetic particles, QDs, CNTs, Ag/ Au nanoparticles and Au surfaces and polymeric materials. The photosensitive aminoacid monomer linkers can react via chemically and biocompatible to a lot of different micro and nano-surface and then to the protein when they act as a single-step cross-linking reaction using irradiation. The photosensitive conjugation based on click biochemistry can be carried out at mild conditions, independent of pH and temperature, without affecting conformation and function of protein.
