As nanopart\u00edculas – pequenas part\u00edculas de mat\u00e9ria que t\u00eam entre 1 e 100 nan\u00f4metros de di\u00e2metro e s\u00e3o indetect\u00e1veis \u200b\u200bpelo olho humano – t\u00eam sido apresentadas como uma forma de encapsular ingredientes farmac\u00eauticos ativos usados \u200b\u200bno tratamento do c\u00e2ncer.<\/p>\n

Esse avan\u00e7o vem com a not\u00edcia de que cientistas russos da National Research Technological University (NITU) MISiS e da Nikolay Pirogov Russian National Research Medical University t\u00eam desenvolvido uma nova abordagem para o tratamento de certos tipos de c\u00e2ncer.<\/p>\n

De acordo com um estudo publicado na revista Pharmaceutics , a nova abordagem baseia-se na utiliza\u00e7\u00e3o de nanopart\u00edculas que entregam uma subst\u00e2ncia m\u00e9dica ativa, como a quimioterapia, diretamente no tumor. Como eles n\u00e3o liberam o medicamento at\u00e9 atingir o interior de uma c\u00e9lula tumoral, isso evita que os medicamentos danifiquem os tecidos saud\u00e1veis \u200b\u200bao redor do tumor.<\/p>\n

Segundo Timur Nizamov, pesquisador j\u00fanior do Laborat\u00f3rio de Nanomateriais Magn\u00e9ticos Multifuncionais, as propriedades magn\u00e9ticas dessas nanopart\u00edculas aumentam a possibilidade de sua entrega direta \u00e0 zona tumoral por meio do controle de campos magn\u00e9ticos.<\/p>\n

No futuro, segundo Nizamov, o desenvolvimento dessa tecnologia permitir\u00e1 criar o que ele chamou de “arma de alta precis\u00e3o ” contra tumores malignos, operando segundo o princ\u00edpio “disparar e esquecer”.<\/p>\n","protected":false},"excerpt":{"rendered":"
