Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]
What are next-generation bio sensing techniques? Part 1
With the ease that people can travel around the world, viruses spread through droplet transmission are one of the most dangerous causes of infectious diseases. The COVID-19 pandemic made this point quite clear. One of the obvious responses to prevent a reoccurrence of this type of situation is effective virus detection technology to prevent the […]
What’s new in color sensing?
Advancements in color sensing technology and its increased use in industrial automation are increasing the adoption of color sensing technology across several industries. Color sensing devices are extensively used to detect the color of the surface and to monitor the color consistency in packaging, textile production and automotive applications. For example, in the packaging industry, […]
What’s the outlook for chemical sensors?
The current emphasis on providing products and materials with fewer environmental effects will have a direct impact on the chemical industry and chemical sensors. Obviously, this starts with, but is certainly not restricted to, reduced CO2 emissions. Chemical sensors have a wide range of applications, including healthcare, industrial, biotechnology, and household sensing requirements such as […]
Are you OK?
Think carefully before you answer, especially if the answer is no. This could lead to a variety of medical tests to measure different parameters to determine the nature of your out of sorts health situation. Of course, you could be among the many people who can not only say I’m feeling good or even great, […]
What makes a stethoscope smart?
Unlike the analog stethoscope used by doctors for over 100 years, the digital stethoscope appeared in 1960. According to DataM Intelligence, a market research and business intelligence firm, the Electronic Stethoscope Market size was valued at USD 342.1 million in 2021 and is estimated to reach at a compound annual growth rate (CAGR) of 8.20% […]
How has hearing aid sensing changed?
With the U.S. Food and Drug Administration (FDA) rule enabling access to over-the-counter (OTC) hearing aids going into effect on Oct. 17, 2022, many people will want to know the answer to this FAQ [1]. The ruling allows individuals to buy a hearing aid without a medical exam, prescription or professional fitting. Intended to help […]
What’s new in glucose sensing?
Key driving forces for new or next generation products include (1) critical need, (2) broad, global usage and (3) sufficient volume requirements to justify R&D expenditures. Glucose sensing/monitoring meets these criteria and more. In the United States alone, the American Diabetes Association (ADA) says over 133 million Americans have diabetes or prediabetes [1]. According to […]
What’s happening in sensorization? Pt 2
While sensorization, the increased use of sensors to improve products and specific market segments as described in part 1, is achieving its desired goal, there are some unforeseen disadvantages. For example, in a recent McKinsey & Company report about software and electronics in the automotive industry, the authors predict that the development of the autonomous […]
What’s happening in sensorization?
The term sensorization may have been used before the introduction of the Apple iPhone but it certainly has been used more frequently since that milestone [1]. The term identifies how a single device, such as a smartphone, or an application area, such as healthcare, improves with embedded sensors and it has the forward-looking potential of […]
