Targeting radioactive micro/nano fluid preparation

Abstract

A targeting radioactive micro / nano fluid preparation comprises solvent and micro / nano particles suspended in the solvent, is hermetically stored in a radiation-proof container, and injected through a radiation leakage-proof syringe. The solvent and micro / nano particles are both subjected to sterilization treatment. The preparation provided by the invention has the advantages of good targeting effect, good inter-tissue penetrability, easily controllable dosage, simple operation method, and greatly improved tumor treatment effect.

Description

technical field [0001] The invention relates to the technical field of micro-nano materials and DNA markers, in particular to a targeted radioactive micro-nano fluid preparation. Background technique [0002] At present, clinical radiation therapy mainly includes external radiation, internal radiation and radionuclide therapy. External irradiation has relatively low requirements for equipment and doctors’ operating skills, but because the radiation must pass through the skin and normal tissues before it can be absorbed by the tumor, the radiation source needs to be strong and may cause damage to the skin and normal tissues; while internal irradiation can maximize As close to the tumor tissue as possible, the intensity of the radiation source required is small, and the tumor tissue can absorb energy more effectively. However, the current technology makes the internal radiation have relatively high requirements for instruments and operations, and because of the need for a seal...

Problems solved by technology

External irradiation has relatively low requirements for equipment and doctors’ operating skills, but because the radiation must pass through the skin and normal tissues before it can be absorbed by the tumor, the radiation source needs to be strong and may cause damage to the skin and normal tissues; while internal irradiation can maximize As close to the tumor tissue as possible, the intensity of the radiation source required is small, and the tumor tissue can absorb energy more effectively. However, the current technology makes internal irradiation have relatively high requirements for instruments and operations, and due to the need for a sealed source applicator, it is mostly used for surface radiation. Superficial lesions or intracavitary, intraductal, interstitial tumor treatment

Radionuclide therapy is effective and simple, but it is only suitable for tumors in certain organs
