Scientists developed laser-carved microvalves to protect fragile brain catheters from backflow, enabling smooth delivery of therapies. The valves regulate fluid flow through geometry without moving parts, suppressing reverse pressure surges by up to 82%.
Researchers from the University of Osaka developed an analytical tool called acoustic tweezers to investigate the mechanical properties of biopolymer condensates. The study found that changes in the natural movement of a droplet in solution can provide information on the stiffness of the droplet and the state of the molecules inside.
A new method enables scientists to read the genomes of individual cells and viral particles in the environment more quickly and efficiently. The approach, known as environmental microcompartment genomics, increases throughput by an order of magnitude and provides unique insights into the diverse world of marine viruses.
Researchers at City University of Hong Kong announce an advanced sperm selection system that signals a breakthrough in assisted reproduction. The system, called BLASTO-chip, uses microfluidic droplet technology to select live sperm from immotile samples with over 90% accuracy.
Scientists from the University of Tsukuba have created a novel measurement technique to study fluid mixing phenomena, leveraging a selective color imaging method. The technique utilizes ultrasonic waves to levitate and mix small droplets, allowing researchers to capture their mixing state in detail.
Researchers at Xi'an Jiaotong-Liverpool University have developed a sensitive and robust pH sensor that can detect pH variation in just a few microliters of samples. The new sensor uses novel materials and methods to overcome the current method's limitations, which are not sensitive enough or fragile for commercial-scale use.
A team of researchers from the University of Liège has studied the mechanisms governing water droplet speed along fibers. They found that thicker fibers result in lower speeds, but unexpected behavior occurs when two fibers are bundled together, leading to faster droplet movement.
Researchers discovered that Alcanivorax borkumensis biofilms consume oil by stretching droplets into tubes, allowing for efficient oil degradation. Large concentrations of dispersants can harm these biofilms, highlighting the need for further research.
Researchers developed a microfluidic platform harnessing acoustic radiation force to manipulate droplets in air, achieving jump heights of up to 128mm. The platform allows for control over the direction and movement of droplets, enabling potential applications in scientific experiments and three-dimensional displays.
Researchers found that wet masks make it more difficult for respiratory droplets to penetrate and escape the mask, splintering into smaller aerosolized particles. This is because wet masks create additional resistance due to their hydrophobic or hydrophilic materials, making them more effective at stopping droplet penetration.
Researchers at City University of Hong Kong discovered a way to steer the spreading direction of liquids on a surface inspired by the Araucaria leaf. By adjusting the surface tension, they can control the liquid flow direction, with implications for fluidics design and heat transfer enhancement.
Researchers at the University of Central Florida have identified food products that can alter a person's saliva to reduce the transmission potential of airborne pathogens. By adding ingredients like ginger, cornstarch, and xanthan gum to food products, people may be able to make masks more effective or even reduce their need for them.
Researchers successfully mimic nano spatial compartments to create artificial mitochondria, capable of supplying ATP or other useful molecules to cells in damaged or diseased tissues. The artificial organelles are generated from Exosome fusion and can function as energy reserves in the damaged tissues.
