泡沫破裂和声音提供了新的治疗癌症
新方法将抗癌药物使用气泡和声波是利兹大学的发展。项目将使剧毒药物小剂量直接投递到肿瘤,其毒性可以安全地好好利用。如果成功的话,这项技术可以很容易地改编成其他疾病。The project brings together engineers, physicists, chemists and cancer specialists from across the University to work on the new technique. The research will use existing chemotherapy drugs to gain initial proof of concept before adapting the delivery mechanism for use with novel therapeutics being developed at the University to treat colorectal cancer. Tiny gas-filled bubbles just a 1000nth of a millimetre across are already used in medicine to provide a clearer image on ultrasound scanners, because, when they are injected into the bloodstream, they reflect a stronger signal than the surrounding tissue.

但是,某些超声波信号会破灭的泡沫,这一现象,研究人员计划利用一个聪明的癌症治疗。The researchers will attach the drug to microbubbles, along with antibodies that are attracted to the tumour to make the bubbles congregate at the tumour site. Ultrasound will then be applied to the site at the correct frequency, and when the bubbles burst a manageable but effective dose of the drug will be released. An added benefit is that ultrasound can also temporarily rupture cell membranes, helping to get the drug into the cells where it can be most effective.............................
