=== Galactogen ===
'''Galactogen''' is a polysaccharide of [[galactose]] that functions as energy storage in [[Pulmonata|pulmonate]] snails and some [[Caenogastropoda]].<ref>{{cite book | vauthors = Goudsmit EM | date = 1972 | chapter = Carbohydrates and carbohydrate metabolism in Mollusca | veditors = Florkin M, Scheer BT | title = Chemical Zoology | volume = VII Mollusca | publisher = Academic Press | location = New York | pages = 219–244 }}</ref> This polysaccharide is exclusive of the reproduction and is only found in the albumen gland from the female snail reproductive system and in the [[perivitelline fluid]] of egogens have applications within hydrogel structures.

Formed by crosslinking polysaccharide-based [[nanoparticle]]s and functional polymers, galactogens have applications within hydrogel structures. These hydrogel structures can be designed to release particular nanoparticle pharmaceuticals and/or encapsulated therapeutics over time or in response to environmental stimuli.<ref>{{cite journal |last1=Hoare |first1=Todd |last2=Babar |first2=Ali |title=In situ gelling polysaccharide-based nanoparticle hydrogel compositions, and methods of use thereof |url=https://pubchem.ncbi.nlm.nih.gov/patent/US-2021361570-A1 |journal=PubChem |volume=1 |issue=1}}</ref>

Galactogens are polysaccharides with binding affinity for [[bioanalytes]]. With this, by end-point attaching galactogens to other polysaccharides constituting the surface of medical devices, galactogens have use as a method of capturing bioanalytes (e.g., CTC's), a method for releasing the captured bioanalytes and an analysis method.<ref>{{cite journal | last1=Wiegman | first1=Peter | last2=Mulder | first2=Hans | title=A process for applying a coating comprising one or more polysaccharides with binding affinity for bioanalytes onto the surface of a medical sampling device, and the medical sampling device for capture of bioanalytes provided with the coating | url=https://pubchem.ncbi.nlm.nih.gov/patent/WO-2022034027-A1 | journal=PubChem | volume=1 | issue=1 | pages = 101–104  }}</ref>
