At the industry sci-tech achievement matchmaking session of the 2026 Greater Bay Area Science Forum, cutting-edge technologies are shedding their intimidating aura and becoming more accessible. They are not only winning world-class science and technology awards, but also finding ways to benefit the public.

At the booth of The Hong Kong University of Science and Technology (HKUST), Zheng Wenyue, a doctoral student in the laboratory of Professor Nancy Yuk-Yu IP, was introducing her team's blood test for Alzheimer's disease (AD). "With just one drop of blood, we can detect 21 blood proteins simultaneously and identify people at high risk five to 10 years before symptoms appear, with an accuracy rate of over 96%."

The technology won an award of excellence at the 48th International Exhibition of Inventions Geneva. This is what it means to reach the highest levels of scientific achievement. In the past, screening for the disease involved either an uncomfortable lumbar puncture to collect cerebrospinal fluid or costly and complicated PET scans. Now, the process can be reduced to a single drop of blood. That is what it means to bring technology into everyday life.

For technology to truly benefit the public, it must be practical and affordable. According to Zheng, the test is now available at some clinics in Hong Kong, where around 3,000 people have been tested. Each test costs approximately 3,000 HK dollars (2,544.30 yuan). On the Chinese mainland, clinical trials have also been conducted at nine centers, including Beijing Tiantan Hospital.

At the booth of The Chinese University of Hong Kong, Shenzhen, the team led by Academician Tang Ben Zhong presented another example of technology that reaches both the highest levels of innovation and practical application: aggregation-induced emission (AIE) materials.

Their scientific significance lies in the fact that this is a cutting-edge field of research pioneered and led by Chinese scientists on the global stage, with the potential to break through the physical limits of traditional solar energy utilization. According to the team, conventional solar panels can capture only a limited range of wavelengths, leaving much of the sun's energy unused. This breakthrough in foundational materials makes it possible to "slice up" sunlight and put different parts to use. Ultraviolet light is converted into visible light for electricity generation; green light, which most crops cannot absorb, is converted into red light to provide plants with additional light; and near-infrared light is converted into thermal energy for seawater desalination.

The practical value lies in taking the technology beyond the laboratory and putting it to work in the fields. Applied in dozens of mu of tomato fields in Yunnan Province, the new material has increased yields by 10% to 20%, generating an additional 2,000 to 3,000 yuan in income per mu. The benefits are tangible gains that go directly into farmers' pockets.

在湾区看见“顶天立地”的科技

在2026大湾区科学论坛“粤港澳大湾区产业科技成果对接会”上，前沿科技产品正在褪去高冷的外衣。既能拿下世界级科技奖项，又能最终造福于民。

在香港科技大学的展台前，叶玉如实验室博士生郑文悦正在介绍他们团队研发的阿尔茨海默病（AD）血液检测技术。“只需一滴血，就能同时检测21种血液蛋白，在症状出现前5到10年识别高风险人群，准确率超96%。”

这项技术曾拿下第48届日内瓦国际发明展优秀奖，这是“顶天”。过去人们筛查这种病，要么经历受罪的脑脊液穿刺，要么靠昂贵又繁琐的大型PET扫描，如今变成一滴血就能解决的事情，这便是“立地”。

真正的科技惠民，不能端着架子，而是要真正帮着老百姓算好账。据郑文悦介绍，目前，这套检测技术在香港部分诊所落地，完成了约3000人的检测，一次检测的费用大约3000港币（换算人民币为2544.3元）；在内地，天坛医院等9家分中心也已进行了临床试验。

在香港中文大学（深圳）的展台前，唐本忠院士团队研发的“聚集诱导发光（AIE）材料”，则向我们展示了另一种“顶天立地”。

这里的“顶天”，在于它是一项由中国科学家开创并引领的国际前沿赛道，打破了传统太阳能利用的物理极限。据介绍，过去的太阳能板只能截取单一波段，大量光能被白白浪费，而这项底层材料的突破，能够将太阳光“切片”使用。紫外光被转换成可见光，用来发电；多数农作物吸收不了的绿色光被转换成红色光，为农作物“加餐”；近红外光被转换成热能，用来淡化海水。

它的“立地”，则是没有把成果停留在实验室的玻璃柜里，而是深深扎进了土地里。在云南的几十亩番茄地里，这项新材料的应用使其增产10%到20%，每亩增收2000-3000元，成为了落进农民口袋里实打实的真金白银。
