The alcohol detector is the most common electronic nose. The driver blows air into the alcohol detector. The chemical sensor inside the detector measures the alcohol content of the gas. After this chemical reaction is converted into an electrical signal, the police can judge whether the driver is drunk or not based on the displayed result. Because the chemical reaction of alcohol is special and the concentration in the gas to be measured is high, the alcohol content is relatively easy to detect. However, other gases are mostly mixtures of different gas molecules. The concentration of these gas molecules is very low. It is a great challenge to detect the different components of this mixed gas. Researchers from the University of Leuven (KU Leuven) have developed a very sensitive electronic nose using metal-organic frameworks (MOF). “MOF is a bit like a micro-sponge,†explains postdoctoral researcher Ivo Stassen. “The tiny pores of this material absorb a lot of gas.†“We developed a MOF that absorbs phosphates from pesticides or nerve gases, which means that MOF can be used to detect chemical weapons or residues of pesticides in food. This is by far the most sensitive to detect these dangerous chemicals. Sensors. We worked with IMEC to complete the measurement of the sensor, which can detect very low concentrations of harmful substances: one part per billion to one part per trillion." Professor Rob Ameloot added that the sensor can be easily integrated into today's electronic devices. "For example, you can mount MOF as a film on the surface of the circuit, so MOF can be easily installed in a smartphone. Testing pesticides and nerve gas." “The next step will be to broaden the range of applications for this sensor,†Rob Ameloot added. “MOF is able to measure very low concentrations of gas and may therefore be used as a tool for diagnosis, for example by detecting the patient's breathing for early detection. Lung cancer or metabolic syndrome (MS), etc. It can also be used to detect whether food is broken, or to distinguish between true and false wines. In a word, this technology provides us with more observation angles."
Red light therapy (RLT) is a treatment that may aid in the healing of skin, muscle tissue, and other body components. It exposes you to red or near-infrared light at modest intensities. Infrared light is a sort of energy that your eyes cannot see but which your body perceives as heat. Red light is comparable to infrared light, however it is visible.
Hair loss is a common occurrence. In one research, men and women with androgenetic alopecia (a hereditary condition that causes hair loss) gained thicker hair after using an at-home RLT device for 24 weeks. The outcomes were not the same for those who utilized a bogus RLT gadget in the trial.

What's red light therapy? Red light therapy before and after
Low-level laser treatment (LLLT), low-power laser therapy (LPLT), and photobiomodulation are all terms for red light therapy (PBM).
What Is Red Light Therapy and How Does It Work?
Red light treatment involves exposing your skin to a red-light bulb, gadget, or laser. Mitochondria, also known as the "power generators" of your cells, absorb it and use it to produce additional energy. This, according to some scientists, helps cells repair themselves and grow healthier. This promotes skin and muscular tissue repair.
The skin is not injured or burned by red light treatment since it employs very low amounts of heat. It is not the same sort of light used in tanning salons, and it does not expose your skin to UV rays that are harmful to your skin.
What Is It Used For?
Red light treatment has been studied for a long time. However, there aren't many research on it, and no one knows if it's better than other sorts of healing treatments. The use of red light therapy may be beneficial in the following situations:
Dementia. People with dementia who received near-infrared light treatment on their heads and via their nostrils on a daily basis for 12 weeks had improved memory, slept better, and were less irritable.
Pain in the teeth. People with temporomandibular dysfunction syndrome (TMD) experienced decreased discomfort, clicking, and jaw soreness after receiving red light treatment, according to another small study.
Osteoarthritis. According to one research, red and infrared light treatment reduced osteoarthritis-related pain by more than half.
Tendinitis. RLT appears to reduce inflammation and discomfort in persons with Achilles tendonitis, according to a small trial of seven participants.
Wrinkles and other symptoms of aging and damage to the skin. RLT has been shown in studies to aid with wrinkles and skin smoothing. RLT can also assist with acne scars, burns, and sun damage indications.
Even though experts aren't clear how or why red light treatment works, it's usually thought to be safe. There are also no hard and fast guidelines on how much light to use. Too much light can harm skin tissue, while too little can make it less effective.
What Is Red Light Therapy and Where Can You Get It?
At most cases, it's done in a doctor's office. Some salons and dentistry clinics, however, do it as well. You may also purchase a red light treatment gadget on your own. Side effects and injuries are more likely to occur with salon and at-home treatments. If you're considering red light treatment, see your doctor first.
