Summary

Automatic Translation

Automatic Translation

Desorption elektrospray massespektrometri (DESI-MS) er en omgivende metode, som prøver, herunder biologiske væv, kan afbildes med minimal prøveforberedelse. Ved rastering prøven under ionisering sonden, giver denne spray-baseret teknik tilstrækkelig rumlig opløsning til at skelne molekylære egenskaber af interesse inden vævssnit.
