This is the first time I’ve seen a study about nanotechnology perception and awareness from Asia. (As I’m sure this is not the first or the only such study, I lament my language skills once more. Since my primary search is for English language materials with my second language, French, as a very distant second, I am limited to translated materials.)
This piece of research comes from Singapore. From a Dec. 11, 2014 news item on the Asian Scientist magazine website,
A survey published in the Journal of Nanoparticle Research shows that while the Singaporean population is more familiar with nanotechnology than their Western counterparts in the US and Europe, they are also more wary of the risks involved.
Asia is expected to dominate the use and release of nanomaterials into the environment, largely due to the size of the population. Furthermore, the region in general—and Singapore in particular—has invested heavily in nanotechnology research, rapidly translating their findings into industrial and consumer products. However, there has been a lack of studies documenting public attitudes and acceptance of new technologies such as nanotechnology.
To address this gap of information, a team of researchers led by first author Dr. Saji George from the Nanyang Polytechnic (NYP) Center for Sustainable Nanotechnology conducted a survey of 1,080 Singaporeans above the age of 15. Their results revealed that approximately 80 percent had some understanding of nanotechnology.
A June 20, 2014 Nanyang Polytechnic media release provides additional details about the research,
In a recent public perception study conducted in Singapore with 1,000 respondents, researchers from Nanyang Polytechnic’s (NYP) Centre for Sustainable Nanotechnology (CSN) found that 80% of respondents were aware of nanotechnology, while only 40% of them were positive about its benefits. This was shared at the official launch of the CSN today. The event was graced by Mr Derek Ho, Director-General, Environmental Public Health Division, National Environment Agency (NEA).
The Centre is the first-of-its-kind among institutes of higher learning (IHLs) in Singapore. It is dedicated to studying the potential impact of novel engineered nanomaterials, and developing ways to ensure that nanotechnology applications are adopted in a sustainable manner for individuals and the environment. This makes the $1 million facility a key training facility for NYP’s students from the Schools of Chemical & Life Sciences, Engineering, and Health Sciences.
Perceptions influenced by exposure to prior information
The perception study conducted in collaboration with the United Kingdom’s Newcastle University, is part of a worldwide study. [emphasis mine] About 1,000 respondents were surveyed in Singapore. Among them, 80% had some level of familiarity with nanotechnology, while only 40% of them were positive about its benefits. One of the strong determinants that influenced the perception of the public was their prior exposure to news on adverse effects of nanotechnology. This could be due to negative information on nanotechnology carried in the media. Often these are over interpretations of laboratory studies that tend to dampen public confidence in nanotechnology.
“Nanotechnology may be a double-edged sword in some applications. A large proportion of the population is already aware of it, and interestingly, 60% have actually come across negative information on nanotechnology. This points to the need for the Centre for Sustainable Nanotechnology to conduct its work robustly and effectively, to sharpen the benefits, and blunt the risks associated with nanotechnology. This will enable industries to better apply the relevant solutions, and for people to use products containing nanotechnology more confidently. Another impetus for the Centre is that through such studies, companies will learn what consumers are concerned about in specific types of products and how these concerns can be addressed during product design and manufacturing stages,” said Dr Joel Lee, Director of NYP’s School of Chemical & Life Sciences where the Centre is located.
The study also found variations in perception among different socio-demographic groups, and among applications of nanotechnology across different product ranges, for example food, baby products, medicine, clothing, cosmetics, water filters and electronics.
While this is a segue, there’s a very interesting tidbit about silver nanoparticles in this media release,
Smarter Antibacterial Nanotechnology
Since the CSN started operations in 2013, senior lecturers, Dr Saji George and Dr Hannah Gardner, from NYP’s Schools of Chemical & Life Sciences and Engineering, respectively, have studied the effectiveness of nano-silver in eliminating bacteria – which accounts for 30% of commercial nanotechnology – in applications currently available in the market. Nano-silver is largely used as an alternate anti-microbial solution in a range of industries, including clothing, baby products, personal care products and medicine.
Their research findings, now filed as a patent, uncovered that some drug resistant bacterial strains could also develop resistance to silver, contrary to the general notion that all bacterial strains will succumb to it. The duo then designed and developed a cost-effective method to generate cationic polymer coated silver nanoparticles. They observed that these nanoparticles could eliminate pathogenic bacteria regardless of their ability to resist antibiotics and silver.
Dr Lee added, “Nano-silver has captured the attention of industry and researchers. What we hope to achieve with the CSN is two-fold. We aim to be a resource for industries and even government regulatory agencies to tap on to better understand nanotechnology, its effects, and improve on its applications. These would also translate into real-world industry projects for our students and equip them to better serve the industry when they embark on their careers.”
