A mass spectrometry imaging (MSI) source operated at atmospheric pressure was developed by coupling mid-infrared laser desorption and electrospray post-ionization. Exogenous ice matrix was used as the energy-absorbing matrix to facilitate resonant desorption of tissue-related material. This manuscript provides a step-by-step protocol for performing IR-MALDESI MSI of whole-body neonatal mouse.

FAQs
The Taylor cone forms when electrical forces at the liquid surface overcome surface tension near the capillary. Its pointed shape supports emission of a fine liquid jet, which then breaks into electrically charged droplets. This transition determines how the feed leaves the capillary and enables controlled atomization for subsequent deposition, particle formation, or delivery.
Conductivity, viscosity, concentration, and solvent composition are key adjustable properties. Together, they affect how the liquid responds to the electric field, how readily the jet breaks into droplets, and how the payload concentrates during solvent loss. Changing these variables allows researchers to tune droplet size and the morphology of the resulting material.
Solvent evaporation progressively concentrates the dissolved or suspended payload inside the charged droplets. The extent and behavior of this concentration influence the material produced after atomization, including its morphology. Controlling solvent composition therefore helps connect the initial liquid formulation with the physical characteristics required for deposition, delivery, or engineered particle fabrication.
A researcher prepares a liquid feed containing the selected dissolved or suspended material, places it near a capillary, and applies an electric field. Electrical forces create a Taylor cone and emit a fine jet, which breaks into charged droplets. As the droplets travel and solvent evaporates, the concentrated material can be deposited or collected for further use.
These solutions are useful when a bioengineering process requires controlled formation or delivery of material in charged droplets. The feed can be adjusted through conductivity, viscosity, concentration, and solvent composition to influence droplet size and product morphology. Such tunability supports cell encapsulation and drug delivery by linking formulation conditions with the desired engineered product.
The approach supports several outcomes, including biomaterial coatings, engineered particles, and fibers, in addition to cell-encapsulation and drug-delivery formats. Its value lies in controlling how a liquid feed becomes droplets and how evaporation concentrates its payload. Researchers can therefore select solution conditions according to whether the goal is deposition, particle formation, or material fabrication.
