The research was conducted by Gi Hun Lee, a teaching assistant at Chung-Ang University.

Este manuscrito introduz um método robusto de fabricar micropoços côncavos, sem a necessidade de instalações complexas de alto custo. Usando a força magnética, esferas de aço e uma matriz do através de-furo, várias centenas de micropoços formaram-se em um substrato de polidimetilsiloxano (PDMS) 3 x 3 cm.

O objetivo geral deste método é fabricar micro poços esféricos côncavos utilizando esferas metálicas de travamento automático assistidas por força magnética. Olá, meu nome é Gi Hun Lee e sou assistente de ensino na Universidade Chung-Ang. O que nos interessa em nosso laboratório é fabricar vários dispositivos e plataformas em microescala para aprimorar nossos estudos sobre o desenvolvimento de um instrumento biológico, sua cultura e novas microestruturas.

Um de nossos interesses de pesquisa é o desenvolvimento de novos microdispositivos e metodologias para contrair isso em um ambiente tridimensional. Chamamos isso de cultura. A cultura é muito útil para entender a resposta tridimensional, porque é mais semelhante ao tecido real do que a cultura planar bidimensional convencional.
