New Material: Nanozymes



Nanozymes are a new material used in the field of detection. They have high catalytic activity, high adaptability and high stability. Scientists are interested in designing and preparing efficient nanozymes for food detection.

Professor Huang Qing is from the Hefei Institute of Physical Science of the Chinese Academy of Sciences. Recently, his team prepared a few Cu metal organic framework (MOF) nanozymes. The particles utilized low temperature plasma (LTP) technology.

This study was recently published in Biosensors and Bioelectronics.

These nanozymes mimic the activity of Laccase and are found to have different base ligands. Nanozymes showed different responses to five common bioactive substances typically found in food. Huang and his team discovered a sensor that will be used for intelligent sensing. It will identify the bioactive components in food. 

These encoded array sensors are capable of high-throughput and are extremely sensitive. The sensors employ both rapid identification of food particles and quantitative analysis of substances. 

Nanozymes can induce color change. With these new sensors, a color change can easily be seen using a smart phone! This allows for completely portable and intelligent rapid food detection. 

This study shows new way to prepare systematic nanozymes. It also provides a convenient and intelligent method for food inspection.

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

Image
  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

Novel Acoustic Wave Discovered

Image
  A new diffraction phenomenon was researched and published on January 14, 2025. The team was led by Tohoku University with collaboration from the Japan atomic energy agency and the RIKEN Center for emergent matter science. Surface acoustic waves (SAWs) are elastic vibrations. They travel along the surface of materials, not unlike ripples on a pond. SAWs are an important part of frequency filters used in every day devices like our cell phones. These devices change electrical signals in vibrations, or ripples. This occurs because of the piezoelectric  effect and it enables efficient signal processing. During this experiment, the team created a periodic array of magnetic nanoscale materials. The magnetic array is a sort of specialized grating that the waves passed through. The scientists were surprised. Instead of the usual symmetric defraction, the team saw something different. They observed a completely new, asymmetrical diffraction of SAWs called ‘non-reciprocal defraction’....
