2013
In this article we describe different techniques for microfluidic rapid prototyping platforms. The proposed techniques are based on ultraviolet (UV) sensitive and temperature curing epoxies, polydimethylsiloxane (PDMS) based tubing, wire-bonding, and anisotropic adhesive films. The assembling procedures presented are developed for both one-time use devices as well as reusable microfluidic systems.

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture. The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

ATP Driven Pumps III: V-type Pumps

2023
V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient. The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...

ATP Driven Pumps II: P-type Pumps
0 Views •
2023
The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V. A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...
FAQs
A prototype is evaluated by controlling flow rate, pressure, fluid viscosity, power input, and component geometry rather than examining operation under unspecified conditions. Changing these variables can reveal whether fluid transport remains reliable across the intended operating range. Comparing measured behavior under defined conditions helps determine whether the design meets its performance requirements.
Component geometry is one of the variables engineers control because it can affect how effectively the prototype transports fluid. Testing different geometries alongside flow rate, pressure, viscosity, and power input helps isolate design-related causes of poor performance. This approach can expose inefficient actuation or unstable flow before engineers commit to a final device.
Flow rate and pressure provide measurable indicators of how a pump performs under defined conditions. Engineers control and record these variables, then compare the results with design requirements. This comparison shows whether the prototype can move fluid as intended and helps distinguish acceptable operation from problems such as unstable flow or inadequate transport.
Early testing can expose leakage, clogging, inefficient actuation, and unstable flow. These problems matter because they indicate that the design may not transport fluid reliably under its intended conditions. Finding them during prototyping allows engineers to revise the design and reassess performance before committing resources to a final device.
The workflow begins by designing and fabricating an early pump model, followed by testing under defined operating conditions. Engineers control variables such as flow rate, pressure, viscosity, power input, and geometry, measure performance, and compare the results with design requirements. They can then use the findings to identify problems and guide subsequent design iterations.
Testing should include controlled values for flow rate, pressure, fluid viscosity, power input, and component geometry, together with measured pump performance. Using defined conditions makes results easier to compare with design requirements and across iterations. It also helps determine whether observed issues arise from the prototype itself or from changing test conditions.
In bioengineering, pump prototypes support technologies that require precise and dependable fluid transport. The overview identifies laboratory instruments, microfluidic systems, and drug-delivery devices as key applications. Prototyping helps assess whether an early design can transport fluids reliably in these settings before development proceeds toward a final device.
Prototype results provide evidence for deciding whether a design satisfies its intended operating requirements. Measurements can show reliable transport or reveal leakage, clogging, inefficient actuation, and unstable flow. Engineers use these findings in an iterative cycle, refining the design and retesting it before selecting a final configuration for a bioengineering application.
