Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...

Electron Configurations

Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest energy available), Pauli exclusion principle (no two electrons can have the same set of four quantum numbers), and Hund’s rule of maximum multiplicity (whenever possible, electrons retain unpaired spins in degenerate orbitals). The relative energies of the subshells determine the order in which atomic orbitals are filled (1s, 2s, 2p, 3s, 3p, 4s,...

Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation. Control-system compensation involves various configurations, most commonly series or cascade compensation, in which the controller aligns...

The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...

Förster resonance energy transfer (FRET) imaging is a powerful tool for real-time cell biology studies. Here a method for FRET imaging cells in physiologic three-dimensional (3D) hydrogel microenvironments using conventional epifluorescence microscopy is presented. An analysis for ratiometric FRET probes that yields linear ratios over the activation range is described.
FAQs
Optical properties determine how readily illumination passes through or contrasts with the hydrated material. A suitable imaging modality and configuration must therefore account for the hydrogel’s appearance as well as the features being examined. Matching these characteristics improves separation of hydrogel structure from embedded biological components, making measurements of distribution and organization more interpretable.
Magnification controls the apparent size of features, while spatial sampling determines how much structural detail the configuration can resolve. These settings should correspond to the scale of the hydrogel features under study. Appropriate choices help reveal pore architecture or cell organization without producing images that are too coarse for analysis or unnecessarily focused on detail irrelevant to the experiment.
Illumination and contrast adjustments increase the distinction between the hydrogel matrix and labeled biological components. This distinction is important when the hydrated material has low inherent contrast. Carefully configured imaging can make the distribution of embedded components easier to identify, supporting clearer interpretation of cell organization and other biological patterns within the scaffold.
Using consistent imaging settings reduces variation caused by the visualization process rather than by the scaffolds themselves. Comparable magnification, illumination, contrast, and spatial sampling help researchers evaluate structural differences across designs more reliably. This consistency is especially valuable when interpreting changes in pore architecture, swelling, degradation, or the organization of cells within bioengineered materials.
Begin by considering the hydrogel’s optical properties and the labels used for embedded biological components. Select an imaging modality that can reveal those features, then organize magnification, illumination, contrast, and spatial sampling around the intended analysis. Applying the same configuration across comparable samples creates a consistent basis for examining structure, distribution, and biological organization.
A suitable configuration can support examination of pore architecture, swelling, degradation, and cell organization. These outcomes describe both the scaffold’s physical behavior and the arrangement of biological components within it. Viewing them together helps researchers connect hydrogel structure with changes occurring during bioengineering experiments, rather than evaluating material appearance or cellular organization in isolation.
The approach is useful for characterizing scaffold designs and interpreting tissue-engineering or drug-delivery experiments. Imaging settings that resolve the matrix and its embedded components can reveal how a material’s structure, distribution, or biological organization changes across samples. Those observations provide visual evidence for comparing engineered systems and assessing features relevant to their intended use.
