没有什么比突然失明更令人痛苦的了。混有甲醇的酒精饮料是发展中国家的灾难,会导致失明,甚至死亡。这些危险饮品来自条件恶劣的烧酒作坊,犯罪者为了谋取暴利加入甲醇降低酒精含量。由于掺加甲醇并不会改变酒的味道、颜色和气味,所以时至今日都很难提前知道面前的酒是否有毒。哥伦比亚科学家开发了一种能够反复使用的无线芯片(如图) Nothing is more painful than a sudden loss of sight.

These dangerous drinks come from harsh conditions of Shochu workshop, criminals in order to reap huge profits by adding methanol to reduce alcohol content. Since adding methanol does not change the taste, color and smell of wine, it is difficult to know in advance whether the wine in front is toxic or not.
