未来医学很少涉及探索性的外科手术,大多是以个体细胞为目标的疗法。医生会利用纳米材料和显微技术,直接在病人身体内部治疗损伤和疾病。照相机通过消化道时进行拍照,并将照片发送给记录仪,然后医生们就能看见消化道里面是否长有肿瘤或是患有溃疡。纳米壳是一种微小的、表面涂着一层黄金的球体。这些球体经过设计可对红外光产生反应。科学家已经使用纳米壳来消灭肿瘤。这些纳米壳在癌细胞里面集合。当红外光照射这些癌细胞的时候,纳米壳就会变热,从而杀死癌细胞,而健康的细胞却毫发无损。 Future medicine rarely involves exploratory surgery, mostly therapies that target individual cells. Doctors use nanomaterials and microscopy to treat injuries and diseases directly inside the patient’s body. The camera takes a photo while passing through the digestive tract and sends the photo to the recorder. Then the doctor can see if there are tumors or ulcers in the digestive tract. Nano-shell is a tiny, coated with a layer of gold balls. These spheres are designed to react to infrared light. Scientists have used nanoshells to eliminate tumors. These nanoshells gather in cancer cells. When infrared light shines on these cancerous cells, the nanoshells heat up and kill cancer cells, leaving healthy cells intact.
