有一天,纸作的诊断工具可以像印刷报纸那样大批生产,成本只有3到5美分。成本低廉、使用简便、足够结实、能在边远地区使用的诊断工具可以在贫穷地区挽救许多人的生命。为了制造出这样的装置,哈佛大学的乔治·威特塞斯教授(George Whitesides)将先进的微流体学与人类最古老的工艺之一——纸张——结合起来,从而制成了一种多用途的、一次性的检测盒,它只需少量的尿液或血液就可得到传 One day, paper-based diagnostic tools can be mass-produced like newspapers, at a cost of three to five cents. Cost-effective, easy-to-use and robust enough diagnostic tools that can be used in remote areas can save the lives of many in poor areas. To make such a device, George Whitesides of Harvard University combined advanced microfluidics with paper, one of the oldest of mankind, to create a Uses, disposable test cartridges that can be dispensed with only a small amount of urine or blood
