Por eso, los investigadores trabajan para crear mas medicamentos, como los que se fabrican a partir de ARN mensajero (ARNm), que puedan pulverizarse e inhalarse. Un estudio publicado en la revista Journal of the American Chemical Society informa sobre los avances para hacer posible los medicamentos de ARNm inhalables. Los investigadores indican que la nanoparticula de polimero lipidico, que es estable cuando se nebuliza y libera aerosoles (gotitas liquidas) en los pulmones de ratones de forma satisfactoria, se optimizo para contener el ARNm.
