Formulation of solid nano-sized particles in a gel-forming system
First Claim
1. A tissue marker formulation comprisingi) a plurality of solid in-organic particles having a (number) average diameter of 1-500 nm, andii) an organic gel-forming system,wherein the organic gel-forming system undergoes gel-formation when injected into the body of a mammal, and wherein the formulation is imagable,wherein said plurality of solid in-organic particles comprise, one or more X-ray contrast agents, radioactive compounds, paramagnetic compounds, fluorescent compounds or ferromagnetic compounds, or any mixture thereof, andwherein the viscosity of the formulation is less than 10,000 centipoise (cP) at 20°
