The invention belongs to the technical field of medicines and discloses melittin complex nanoparticles for oral administration and a preparation method thereof. Water-soluble melittin and an amphiphilic substance are dissolved into a hydrosolvent A to form a hydrophobic protein ion pairing complex; the complex and a suitable polymer material are dissolved into a nonaqueous solvent B; an emulsion solvent diffusion method in a liquid phase is adopted to wrap the complex into the polymer material; and microparticles with the particle diameter between 10 and 1000nm are formed after the solvent is volatilized. The hydrosolvent A is distilled water, double distilled water, deionized water, physiological saline, or a phosphate buffer solution or an acetate buffer solution or a Tris buffer solution with the pH value of between 1 and 11; and the nonaqueous solvent B is a single or mixed solvent of alcohol, acetone, ethyl acetate, methylene dichloride, chloroform and dimethyl sulfoxide. The complex has high fat solubility, and the encapsulation rate of the nanoparticles is more than 90 percent. The preparation process is mild and can assure the biological activity of medicines. The preparation method is suitable to prepare oral administration preparations.

The invention provides ion-selective sensors capable of selectively measuring ions, e.g., Na⁺, K⁺, Cl⁻, etc., in the cytosol of a single living cell. The sensor comprises one or more quantum dots or a fluorescent dye, a pH-sensitive dye, and optionally an ion-selective component such as an ionophore. These elements may, for example, be disposed in a polymer matrix. The polymer matrix comprises an internalizing moiety which enables the sensor to localize within the cytosol of a cell. The internalizing moiety comprises a small molecule or peptide such as an amine, antepennepedia, mastoparan, or melittin that react under acidic conditions to release a sensor from the confines of a endosome. Once in the cytosol the sensors may detect ionic analytes by selective ion extraction by the polymer, thereby inducing a pH change within the sensor which in turn changes the absorbance of the pH-sensitive dye. The change of absorbance may in turn attenuate the intensity of detectable emissions, e.g., fluorescence, from the quantum dot or dye by directly absorbing its fluorescence emission.
