Collecting and transporting biological samples in the field can be challenging. Traditional methods often require cold storage, centrifugation, and liquid handling; tools not always available in remote or harsh environments. Nobuto blood filter strips offer a simple, portable, and reliable solution for collecting, drying, and transporting blood or serum samples without a cold chain [1].

Safety is at the core of the Food and Beverage industry, which is why it operates under strict regulations. The FDA upholds these standards to ensure that every product that reaches the market is safe for consumers. 

Produced water from oil and gas operations is among the most challenging water streams to treat. Its extreme salinity and complex chemistry make conventional methods inefficient and costly. As water scarcity grows, researchers are turning to advanced reverse osmosis (RO) technologies that can manage these harsh conditions more sustainably. 

On International Coffee Day (October 1), there’s no better reminder of coffee’s cultural power than a story straight from Italy itself — the birthplace of espresso. In Venice, a city built on water, one café has taken “a taste of Italy” to an entirely new level by showing how advanced water purification technology can transform even canal water into a cup of espresso. 

Soils associated with industrial operations such as landfills, manufacturing facilities, and the intensive use of agricultural chemicals can be prone to heavy metal accumulation.  Toxic heavy metals such as lead, arsenic, cadmium, and mercury can accumulate in soil, where they are absorbed by crops and plants. As a result, consumption of these crops inevitably leads to heavy metal exposure¹.

Accurate membrane testing starts with a clean, properly conditioned membrane. Whether working with ceramic membrane or flat sheet membranes, pre-conditioning is a critical first step. It removes residual particulates and surface residues that can interfere with initial performance measurements, ensuring that test results reflect the true capabilities of the membrane rather than artifacts from contamination.

Membrane flat sheet test cells and housings are essential tools in research and development laboratories. They allow researchers to quickly gather data on rejection, flux, and fouling behavior, helping accelerate membrane development and application testing. 

In biomedical research, extracellular vesicles (EVs)—especially exosomes—have become a key focus due to their role in intercellular communication. These nano-sized lipid-bilayer vesicles (30–150 nm), secreted by nearly all cell types, transport proteins, lipids, and nucleic acids, positioning them as valuable tools for diagnostics and therapeutics. However, their small size and low abundance in biological fluids make conventional methods for isolation and purification challenging.  Ultracentrifugation is labor-intensive, costly, and can damage exosome structure under high centrifugal forces, while precipitation and size-exclusion chromatography often produce low-purity samples contaminated with proteins and other non-exosomal particles. 

As mRNA-based vaccines and therapies continue to proliferate, the downstream purification process, particularly Tangential Flow Filtration (TFF), has become a critical efficiency and cost focus. Yet, data on optimizing TFF for mRNA is notably scarce, complicating process development. 

As air pollution continues to pose significant threats to public health and the environment, the demand for accurate and efficient air quality monitoring has never been more urgent. Among various pollutants, PM2.5, which are fine particulate matter with a diameter of 2.5 micrometers or less, stands out due to its ability to penetrate deep into the respiratory system and bloodstream, contributing to a wide range of health issues.
