Accurate Modeling of Viruses – Spherical Particle Shape, Size, and Density

Spherical Particle Shape of Coronavirus from CDC

Spherical Particle Shape of Viruses and Droplets: Due to the global pandemic, there has been a big focus on Coronavirus research and a lot of pressure for researchers and scientists to understand how Coronavirus spreads, as well as how we can effectively stop that spread by implementing effective cleaning protocols, prevention of respiratory droplets traveling, disinfecting of surfaces, or…

3 Scenarios When Density of Microspheres Matters in Research

Does Density of Microspheres Matter for Fluid Suspension?

When is the density of microspheres important? Density of microspheres controls the buoyancy of each particle and its behavior in a system or process. Let’s look at three scenarios: (1) suspension of microspheres in a specific fluid, (2) fluid flow, performing flow visualizations, or particle image velocimetry, and (3) simulation or modeling of objects with specific density.

Suspension of Hydrophobic Particles in Aqueous Solution – Density Gradients

Hydrophobic Particles in Solution

Fortunately, there is a simple way to overcome the hydrophobic effect. It is called a surfactant, a detergent, or simply ?soap.? Surfactant is a magical molecule that has both hydrophobic and hydrophilic properties, which coats the particles and helps them mix into water. The same mechanism applies when we use soap to wash greasy dishes or stained clothes.

Microspheres in Drug Delivery Systems – 2 Essential Uses

Polystyrene Microspheres

Benefits of Microspheres in Drug Delivery There are numerous benefits of using microspheres in drug delivery due to their precise uniform dimensions, larger surface area per unit volume, as well as the ability to be surface-functioalized or loaded with active compounds and other additives. Typically microspheres in drug delivery are manufactured out of biodegradable materials such as PLGA, polylactic…

Particle Image Velocimetry and Tracer Particle Visibility

Microspheres in Biotechnology - Modeling of Bacteria Behavior

Particle Image Velocimetry (PIV) expresses a vast field with varying techniques and data acquisition methods. However, the main goal is providing an optical method of flow visualization. The exact information obtained depends on which method is used, with new algorithms and approaches being discovered constantly. There are generally two ways data is obtained PIV and Particle Tracking Velocimetry (PTV)…

Janus Particles – Properties and Applications

Bichromal (half-white half-black or any other color) Microspheres, Janus Particles

What are Janus Particles? Named after two-faced Roman god Janus who looks to both the future and the past, Janus particles are typically microscopic spheres composed of two different regions. Originally the term “janus particles” was used in reference only to particles that had a hydrophobic surface on one hemisphere and a hydrophilic surface on another. The first “Janus…
