16歲仔 玩printer玩出大發明


如果年輕人肯細心啲，其實係可以有能力創造藍海市場，甚至改變世界，因為好多令社會改進嘅力量，只係源於人類某一樣好基本嘅生活需要。

例如心臟病係全球人類死亡的主要原因之一，及早確診，有助病人改善生活習慣。 外國有位16歲年輕人，正正係因為有此需要，做咗個小發明，有望解決標準診斷法太昂貴呢種問題。

佢叫Adriel Sumathipala，爺爺係佢未出世時，因為心臟病過咗身，而佢家族本身因為有心臟病病史，所以長久以來佢都好希望有種又平又方便嘅方法可以幫到普通嘅人去驗，就好似幫自己嫲嫲咁，檢測心臟病。

近日，佢喺生物老師嘅幫助下，發明咗一種多重生物標記診斷法，不僅簡單迅速、成本極低而且攜帶方便，點做到嘅呢？

佢原來只係利用打印機咁簡單嘅工具，用來檢測氧化低密度脂蛋白水平（Ox-LDL）來檢測心臟健康狀況，詳細運作，可以Click入去了解一下。

據佢講，呢種檢測方式唔單只可以將嗰檢測成本下降到每次0.02美金，仲可能比傳統方式更加準確！佢因為呢個發明，目前已經入咗圍2015年嘅Google science fair，認真拭目以待。

Adriel Sumathipala is a self-described tinkerer.

The 16-year-old says the trait runs in the family: His grandfather, who died of a heart attack before Sumanthipala was born, also loved to build things too.

Once Sumathipala learned that he and his family were also at risk for the disease that caused him to know his grandfather solely through "stories and grainy photos," he tried to stick to a regimen of exercise and healthy eating.

But he felt frustrated that he had no way to monitor the effectiveness of his lifestyle changes, because today's cardiac diagnostic tests require expensive lab testing to measure cholesterol levels.

So, the teen set about creating a on-site, super low-cost, rapid heart disease test that ultimately won him a spot as one of Google's 20 Global Science Fair finalists.

Instead of measuring cholesterol, his test would measure oxidized low-density lipoproteins (Ox-LDL), a biomarker that has an even stronger correlation with cardiac disease.

"I envisioned a diagnostic that would place vital health data in the hands of doctors and patients and thus establish the framework for a personalized medicine revolution," he writes.

With the help of his biology teacher, Sumathipala spent two years trying to build such a diagnostic system. Ultimately, he was able to hack an inkjet printer to deposit enzymes onto two Ox-LDL sensors that he developed. The paper sensor could then indicate whether the enzymes have high or low concentrations of the cardiac disease biomarker Ox-LDL. (Learn more about the project here.)

Sumathipala estimates that the paper-based sensors and the repurposed printing system could bring the price of tests down to only about $0.02, with test results taking minutes instead of days to show themselves.

Sumathipala is one of 22 incredibly intelligent teenagers who made it to this year's Google Science Fair finals. Google will announce the top project in September; the winner gets a 10-day trip to the Galapagos Islands and $50,000 in scholarship funding.

"There’s a different kind of inspiration that comes from helping the people you love most," he writes. "It doesn’t come in a moment of cerebral realization or with the flickering of an imaginary light bulb. It’s a continuous and unlimited inspiration. The kind of inspiration that pushed me through late nights in the lab, kept me going after innumerable failures, and stopped me from giving up my work."
