Abstract

The present invention relates to: a paper-based three-dimensional structure microchip enabling a target antigen to be detected, without external power, by means of a single sample injection through fluid velocity and direction control and the three-dimensional structure of the chip; and a method for detecting a target antigen by using same. The present invention can provide a paper-based three-dimensional structure microchip enabling a target antigen to be detected, without external power, by means of a single sample injection through fluid velocity and direction control and the three-dimensional structure of the chip. Unlike a fluid moving by being absorbed into paper in a conventional method, a fluid in the present invention moves along microtubes (microfluidic channels) made of a patterned film so as to increase in moving speed. Additionally, in the present invention, the velocity and direction of a fluid can be controlled through hydrophilic surface treatment on the paper at the lower part of microtubes and control of the width and length of microtubes. In the present invention, the path through which a substrate solution flows and the path through which a sample and a washing solution flow are located on different planes (3D structure, bridge structure) such that the paths are not physically in contact with each other, and thus seeping leakage of the sample or the washing solution into the substrate solution path (substrate solution microtube) can be fundamentally prevented. That is, a 3D microchip structure of the present invention can reduce signal noise and substrate solution waste caused by leakage of the sample or the washing solution by preventing enzymatic reactions from occurring in a region other than that of a reaction pad.

Abstract

The present invention relates to a method of producing glutathione, wherein photosynthetic membrane vesicles and enzymes catalyzing glutathione synthesis are combined and glutamate, cysteine and glycine are used as reaction substrates. As enzymes catalyzing glutathione synthesis, γ-glutamylcysteine synthetase and glutathione synthetase may be used together, or bifunctional glutathione synthetase may be used alone. According to the conventional methods, there is a problem in that expensive adenosine triphosphate should be continuously supplied when glutathione is produced. However, according to the present invention, since photosynthetic membrane vesicles are used as a source to regenerate adenosine triphosphate, it is possible to continuously produce glutathione without additionally adding adenosine triphosphate, thereby reducing production costs of glutathione.

Abstract

The present invention provides a sustained-release implant for treating eye diseases, having a predetermined size of a three-dimensional shape since albumin nanoparticles containing a drug for treating eye diseases are freeze-dried, compressed and coated. The implant of the present invention can have a predetermined mechanical strength since a nanoparticle powder is compressed, and can also gradually decompose, because of the characteristic surface of a frozen and compressed structure, from the surface to the center thereof. In addition, since the implant of the present invention is coated with a polymer, the mechanical strength of the implant can be further improved, and since a coated polymer material is first decomposed even if the implant is located within the eyeball for a long time, the decomposition of the albumin nanoparticles and a drug release speed can be delayed. Additionally, albumin molecules are gradually released and delivered to ocular tissue and, particularly, to the retina by the decomposition of the nanoparticles in the implant of the present invention, and thus effects (of albumin molecules themselves) such as the protection of nervous tissue and the delay of the death thereof can also be expected.

Abstract

The present invention relates to a microbubble-nanoparticle complex which can be simultaneously used as an ultrasound contrast agent, a photodynamic therapeutic agent, and a chemical drug therapeutic agent, and which can selectively transfer drugs and photosensitizers to specific cancer tissue through an ultrasound response; and to an anticancer therapeutic agent comprising the same. Since the complex of the present invention contains a gas for an ultrasound contrast agent and a photosensitizer substance inside the microbubbles, and nanoparticles bonded to the surfaces of the microbubbles contain a drug, the complex can be used simultaneously as an ultrasound contrast agent, a photodynamic therapeutic agent, and a chemical drug treatment agent. In addition, when an ultrasonic wave is irradiated, the complex of the present invention can provide an ultrasound image of a lesion tissue by using the gas filled in a microbubble core part, as well as break the microbubbles into smaller size micelles or liposomes to efficiently infiltrate and accumulate the drugs and the photosensitizers into the lesion tissue.
