More particularly, it provides a polymersome comprising (a) a membrane, which comprises a block copolymer of poly(styrene) (PS) and poly(ethylene oxide) (PEO), wherein the PS/PEO molecular weight ratio is higher than 1.0 and lower than 4.0; and (b) a core which encloses an acid and at least one pH-sensitive dye. Compositions, strips and kits comprising the polymersomes are also provided along with methods of quantifying ammonia in a sample using the polymersomes, compositions and kit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of making a polymersome","description":"The present invention provides polymersomes comprising amphiphilic block-copolymers and their use to quantify ammonia in samples (e.g., body fluid samples).
