Desenvolvimento de equipamento LED para aplicação em cultura celular

O estágio realizado em parceria entre o Departamento de Física e Biofísica do IBB-UNESP e o Hemocentro de Botucatu da FMB-UNESP teve como objetivo desenvolver um novo equipamento de luz LED capaz de interagir com culturas celulares. Desta forma foi desenvolvido um equipamento com luz azul e luz vermelha. A luz azul é responsável por inibir o crescimento celular, a luz vermelha é responsável por aumentar o crescimento celular. O equipamento consiste de uma fonte, e dois conjuntos com três LEDs cada. A cultura celular escolhida foi a de Miemola Murino (NS1), uma linhagem que possui alta taxa de crescimento e que foi mantida em estufa e meio de cultura, (simulando condições normais de sobrevivência), sendo irradiada três vezes ao dia. As amostras foram coletadas e contadas em câmara de Neubauer. Os resultados obtidos, quando comparados com o controle, não apresentaram significativa diferença de crescimento quando irradiados com luz LED vermelho. Porém quando comparados o grupo controle com o grupo irradiado com LED azul, notou-se uma significativa redução da quantidade de células a partir do sétimo dia de irradiação. Acredita-se que a ineficácia dos LEDs vermelhos ocorreram pois utilizamos células com metabolismo bastante elevado, dificultando um aumento ainda maior da taxa de crescimento. A redução da população de células azuis ocorre pois a radiação interage com a membrana celular, causando a quebra dessa membrana e conseqüente morte da célula. Outra via para a morte é a lesão causada no DNA das células, que ocorre quando a luz azul é absorvida pela molécula
