Abstract:
The present invention relates to a gas-generating micelle prepared by coupling a polyethylene glycol derivative and an alkyl chloroformate. The gas-generating micelles according to the present invention are circulated in the body and deposited on the disease site to generate carbon dioxide, and thus a more enhanced ultrasonic diagnostic image can be obtained.

Claim (Index 8):
A method of preparing a gas-generating micelle including a compound represented by the following Formula 1, the method comprising:\n mixing polyethylene glycol and an alkyl chloroformate to synthesize a polyethylene glycol derivative; and dissolving the polyethylene glycol derivative in one solvent selected from acetonitrile, methylene chloride, chloroform, and methanol or in a solvent mixture of two or more selected therefrom and then evaporating the solvent(s), wherein R 1  is a C1 to C2 alkyl group, H, \u2014NH 2 , or COOH, p is an integer ranging from 12 to 227, and q is an integer ranging from 2 to 14.
