Zusammenfassung:Provided herein are methods and integrated devices for improved sequencing of nucleic acid and peptide biomolecules. The present disclosure relates to improved mechanisms for protecting a luminescent label from photo-induced damage through the use of quenching moieties. Further provided herein are methods for improved immobilization of quenching moieties and other molecules of interest through functionalization with chemical moieties, such as click chemistry handles, capable of participating in cross-linking reactions. Quenching moieties may be immobilized to the surface of a sample well in a sequencing substrate or apparatus in a manner that minimizes or eliminates photobleaching of the labeled molecule. The disclosed methods provide for minimized photodamage, increased sensitivity, accuracy and length of reads during nucleic acid and polypeptide sequencing.
