may not be restricted to a single phase but may be a multiple phase wherein a vapor phase a liquid phase or liquid crystal is suitably mixed therewith the second fluid 12 can be adhered to the outlet port 31 through an interaction between the channel 3 and the second fluid 12 containing an emulsifier 14 the second fluid 12 may not be restricted to either water or oil as for water it is possible to employ pure water distilled water or an aqueous solution containing various materials as for oil it is possible to employ hydrocarbons such as hexane octane isooctane decane dodecane hexadecane cyclohexane etc a hydrophobic solvent such as chloroform etc a hydrophilic solvent such as methanol butanol acetonitrile etc and aromatic hydrocarbons such as benzene toluene etc these solvents can be employed singly or as a mixture further in order to dissolve a water soluble living matter related substance in the second fluid 12 a small quantity of water may be added to the second fluid 12 as long as the solvent or mixed solvent to be employed is capable of dissolving or dispersing the emulsifier 14 there is no limitation with regard to the kinds of solvent mixing ratio and the state of mixture in the manufacture of multiple phase particle for example double emulsion vesicle liposome etc for dds non toxic oil such as non toxic glycerin ethylene glycol ethanol soybean oil etc can be employed as an oil phase as for the second fluid 12 containing an emulsifier 14 it may be constituted by only an emulsifier for example an emulsifier containing at least one material excluding water and oil.
