The analytical ultracentrifuge (AUC) sample cell holds sample and reference buffer and during experiments and is exposed to high vacuum and rotor speeds up to 60,000 rpm. This video will demonstrate the rigorous attention to detail necessary for assembly, loading and alignment of this very important component of an AUC experiment.

Lytic Cycle of Bacteriophages

2019
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the lytic replication...

What are Biogeochemical Cycles?

2019
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles. Biogeochemical Cycles and Decomposition The matter that makes up living organisms, like water, carbon, nitrogen, sulfur and phosphorous, exist in limited quantities within the...

The Water Cycle

2019
The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics. The water cycle begins as the sun warms surface water on the land and in oceans, causing it to evaporate and enter the atmosphere as vapor. The water vapor condenses into clouds and eventually falls as precipitation in the form of rain, snow or hail. After falling back to the...

The Phosphorus Cycle

2019
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems. Biological Phosphorus Cycle Phosphorus is present in many...
FAQs
Each immersion exposes the substrate to a selected biological or synthetic component that can adsorb onto its surface. Alternating between complementary solutions or suspensions allows different components to be incorporated in sequence. Because the composition can be selected for each cycle, the resulting multilayer structure can be adjusted to provide specific material combinations and surface properties.
Rinsing, drying, or transferring the substrate separates successive deposition steps and helps maintain the intended cycle sequence. These intermediate operations determine when the substrate moves from one solution or suspension to the next. Consistent handling supports organized layer formation, which is important when researchers seek controlled composition, thickness, or incorporation of biological or synthetic cargo.
The method links controlled adsorption at the scale of individual layers with the properties of a larger film, coating, or scaffold architecture. Adjusting the assembled composition and thickness can change surface characteristics and cargo content. This connection allows bioengineers to design material structures whose nanoscale organization contributes to the performance of macroscopic devices.
A typical workflow begins by placing a substrate into a selected solution or suspension so a component can adsorb. The substrate then undergoes rinsing, drying, or transfer before entering the complementary solution or suspension. Repeating this sequence builds the multilayer structure, while the chosen cycle sequence determines the resulting composition and thickness.
Researchers can tune the identity of the biological or synthetic component introduced during each cycle, the sequence of complementary solutions or suspensions, and the number of repeated immersion steps. These choices influence the multilayer composition and thickness. They also help tailor surface properties and determine whether selected cargo becomes incorporated into the assembled structure.
Dip Cycle Assembly supports several bioengineering applications, including tissue engineering, biomaterials development, biosensing, and drug delivery. In these settings, organized films, coatings, or scaffold architectures can provide tunable surfaces and carry selected cargo. The approach is therefore relevant when researchers need to connect controllable material assembly with the functional requirements of a biological or device-based system.
