Abstract

"PARTìCULA DE AçãO MúLTIPLA PARA ESTRUTURAçãO DE MEIOS BIOLóGICOS". Processo para alterar a estrutura superficial de partículas ultra dispersas para permitir que interações predeterminadas aconteçam nos meios biológicos. Em uma concretização preferida da invenção, uma partícula ultra dispersa é submetida à modificação de partícula, permitindo a formação de estruturas sobre as superfícies de uma partícula basicamente esférica, de modo a dirigir suas interações. o processo da invenção permite a formação de saliências de formas diferentes e padrões diferentes de ramificação, ligação de substâncias químicas diferentes e alteração da estrutura eletrónica da superfície na partícula basicamente esférica. A modificação da partícula permite a formação de camadas permitindo que ações seq³ências sejam realizadas pela partícula ou a modificação pode criar mais de um tipo de superfície interativa em cada partícula, o que permite interações diferentes simultaneamente. Estas partículas modificadas encontram aplicação, por exemplo, como substâncias farmacêuticas, cosméticos, preservantes e em muitos outros campos. Emulsões de água-óleo podem ser criadas para uso em cremes para pele e outros cosméticos e aplicações na indústria alimentícia. As partículas podem ser usadas em muitas aplicações envolvendo radiação para reduzir o nível de radioatividade necessário, pelo que, abaixando a exposição. As partículas possuem a capacidade de estruturar meios biológicos pela criação de um sistema biológico de três lados compreendendo um tecido biológico, a partícula e o líquido circundante.
