German to English Tech/Engineering Medical: Dentistry Dentistry

The sentence in which this appears:
"Dies geschieht durch Anleihe an die Glasionomer-Technologie."
The general context is talking about making dental filling materials. Immediately preceding sentences talk about the need for the pH level to be raised during setting time so that you don't get hydrolysis processes.

What I don't understand here is the use of a financial term in a technical context (it seems completely out of place), and also what "an" signifies exactly. Can "anleihen an" mean "to borrow from"? Or does it mean "to lend to"? Any suggestions and/or explanations would be much appreciated.
