A fluoresce\u00edna \u00e9 um composto org\u00e2nico sint\u00e9tico que se apresenta como um p\u00f3 laranja escuro\/vermelho e \u00e9 ligeiramente sol\u00favel em \u00e1gua e \u00e1lcool. \u00c9 amplamente utilizado como um marcador fluorescente para muitas aplica\u00e7\u00f5es.<\/p>\n

A fluoresce\u00edna \u00e9 um grupo fluorescente normalmente utilizado em microsc\u00f3pios, lasers de corante como meio de ganho, dete\u00e7\u00e3o forense e serol\u00f3gica de potenciais manchas de sangue e rastreio de corantes.
