We present a facile method to fabricate a biodegradable gelatin-based drug release platform that is magneto-thermally responsive. This was achieved by incorporating superparamagnetic iron oxide nanoparticles and poly(N-isopropylacrylamide-co-acrylamide) within a spherical gelatin micro-network crosslinked by genipin, in conjunction with an alternating magnetic field application system.

The ability to successfully make solutions is a basic laboratory skill performed in virtually all biological and chemical experiments. A solution is a homogenous mixture of solute dissolved in bulk liquid known as the solvent. Solutions can be described by their solute concentration, a measure of how much solute is present per unit of solution. In this video, a step-by-step procedure for how to make a water-based, or aqueous, solution for biological applications is presented. The video...

Source: Laboratory of Dr. Michael Evans — Georgia Institute of Technology A solution is a homogeneous mixture containing some components in small amounts, called solutes, and one component in a large amount, called the solvent. Solid-liquid solutions contain one or more solid solutes dissolved in a liquid solvent. Solutions are ubiquitous in chemistry: they are used to store and handle small amounts of material, carry out chemical reactions, and develop materials with controllable properties.

General Properties of Solutions

Many common substances around us exist as a solution, such as ocean water, air, and gasoline. All solutions are mixtures of substances that are composed of varying amounts of two or more types of atoms or molecules. A mixture with a non-uniform composition is a heterogeneous mixture, whereas a mixture with a uniform composition is a homogeneous mixture. The components that make the homogeneous mixture are evenly spread out and thoroughly mixed. A solution is a homogeneous mixture that is...
FAQs
Heating allows gelatin molecules to disperse throughout the water. During cooling, they partially reassociate and form a three-dimensional network that retains water. Because this network can form and loosen again with temperature changes, the resulting material is thermoreversible, allowing researchers to create and later modify gelatin-based biological matrices.
Gelatin firmness depends on how much gelatin is present, the temperature of the preparation, and the solution’s composition. Higher or lower values of these factors alter the extent of network formation and water retention. Controlling them helps researchers obtain a material with properties appropriate for surface coating, stabilization, encapsulation, or tissue-engineering studies.
Gelatin can be applied as a surface-coating material to support cell attachment in culture systems. This use provides a biologically relevant interface for investigating cell behavior rather than treating the culture surface as an inert background. The coating therefore helps connect material design with observations of how cells interact with their surroundings.
Preparation begins by combining gelatin with water and applying heat so the gelatin molecules disperse. The solution can then be allowed to cool, enabling partial molecular reassociation and network formation. The selected concentration, temperature, and composition determine whether the preparation functions mainly as a liquid solution, a gel, or a biological matrix.
Researchers can modify the preparation by controlling gelatin concentration, temperature, and composition. These variables influence network development, water retention, and gel firmness. Such adjustments allow the same general material to be adapted for different experimental roles, including a culture-surface coating, a stabilizing preparation, or a matrix used for encapsulation studies.
In biology, gelatin solutions can support cell attachment on culture surfaces, stabilize biological preparations, and provide matrices for encapsulation or tissue-engineering investigations. These applications let researchers examine cell behavior within a controllable material environment while also exploring how gelatin-based systems can be designed for biological studies and biomaterial development.
