Carrier holding micro-substances, system suspending such carriers apparatus for manipulating such carriers and method of controlling positions of such carriers
Carriers hold remote-acting bodies which can be manipulated by a remote force, and also hold a micro-substance which is a target substance of an assay. The remote-acting bodies are manipulated in order to control the positions of the micro-substances, so as to execute assays for various target substances efficiently, at low cost, easily, and reliably. Various aspects of interest include the carriers which hold the micro-substances, a system suspending the carriers, an apparatus for manipulating the carriers, and a method of controlling the position of the carriers.
1. A method of controlling a position of carriers holding micro-substances comprises the steps of:
pouring remote-acting bodies which can be positionally manipulated by a remote force, micro-substances including a target substance of an assay, and carriers having surfaces with a plurality of holes, cavities, concavities or convexities that are sized to be capable of holding the micro-substances and the remote-acting bodies, into a liquid in accordance with a predetermined order,
making the remote-acting bodies and the micro-substances be held in the holes, cavities, concavities or convexities in the surfaces of the carriers by agitating the remote-acting bodies, the micro-substances, the carriers, and the liquid, and
controlling positions of the carriers holding the micro-substances and the remote-acting bodies in the surfaces thereof by applying a remote force to the remote-acting bodies,
the pouring comprising pouring sterilized reductive enzyme into the liquid in addition to the remote-acting bodies, the micro-substances, and the carriers, and
comprising selecting the carriers to be sterilized cellulose-carriers, selecting the liquid to be a sterilized liquid culture medium, selecting the remote-acting bodies to be magnetic particles, and selecting the remote force to be a magnetic field.
2. A method of controlling positions of carriers holding micro-substances according to claim 1 , further comprising controlling the magnetic field so as to control the positions of the carriers in a manner which causes filtering of the micro-substances through separation from the liquid or gas of the carriers with the remote-acting bodies and micro-substances held thereto.
3. A method of controlling positions of carriers holding micro-substances according to claim 1 comprising, prior to the pouring, separately preparing the carriers, the remote-acting bodies, and the micro-substances.
4. A method of controlling positions of carriers holding micro-substances according to claim 1 , comprising selecting the micro-substances to comprise one of bacteria and viruses.
5. A method of controlling positions of carriers holding micro-substances according to claim 1 , comprising selecting the predetermined order to be addition to the liquid culture medium in sequence the sterilized reductive enzyme, the micro-organisms, the sterilized cellulose-carriers, and the magnetic particles.
6. A method of controlling positions of carriers holding micro-substances according to claim 1 , comprising selecting the micro-substances to comprise one of antibiotics and anticancer substances.
7. A method of controlling positions of carriers holding micro-substances according to claim 1 , wherein the agitating includes using a mechanical force.
8. A method of controlling a position of carriers holding micro-substances comprises the steps of:
pouring remote-acting bodies which can be positionally manipulated by a remote force, micro-substances including a target substance of an assay, and carriers having surfaces with a plurality of holes, cavities, concavities or convexities that are sized to be capable of holding the micro-substances and the remote-acting bodies, into a liquid or a gas in accordance with a predetermined order,
making the remote-acting bodies and the micro-substances be independently held in the holes, cavities, concavities or convexities in the surfaces of the carriers by simultaneously agitating the remote-acting bodies, the micro-substances, the carriers and the liquid or gas,
controlling positions of the carriers holding the micro-substances and the remote-acting bodies in the surfaces thereof by applying a remote force to the remote-acting bodies,
selecting the carriers to be cellulose-carriers having therein the plurality of cavities, concavities, convexities or holes,
selecting the remote-acting bodies to be magnetic particles,
selecting the remote force to be a magnetic field,
controlling the magnetic field so as to control the positions of the carriers in a manner which causes filtering of the micro-substances through separation from the liciuid or gas of the carriers with the remote-acting bodies and micro-substances held thereto,
carrying out the agitating in a manner that includes using a mechanical force; and
configuring the carriers so that the holes, cavities, concavities or convexities are large enough to allow the magnetic particles to undergo orientation therein in response to the magnetic field.
