Minimizar la variabilidad en la fracción de partículas dentro de andamios granulares facilita la experimentación reproducible. Este trabajo describe métodos para generar andamios granulares con fracciones de partículas controladas para aplicaciones de ingeniería de tejidos in vitro .

Los materiales granulares, como los andamios MAP, son materiales inyectables porosos hechos de partículas de hidrogel de tamaño micro interconectadas. El control de la fracción de partículas es fundamental para las propiedades del material y las respuestas celulares. Las fracciones de partículas variables en andamios MAP dan como resultado un rango de propiedades de andamio y respuestas celulares, pero esta técnica permite a los usuarios definir la fracción de partículas final en los andamios MAP que crean.

Los andamios MAP se pueden utilizar para promover la reparación y regeneración de heridas complejas, así como para administrar medicamentos. La fracción de partículas, por ejemplo, afecta la velocidad y el grado de infiltración y regeneración celular. Este método se puede aplicar en todas las clases de hidrogeles granulares.
