Titles sold through the Nook Comics service are now available for devices measuring in at seven inches and up, and running the Google operating system.
Android users can gain access to Nook Comics by downloading the app's 3.1 update. Over 600 titles are available on the storefront, many of which are graphic novels from publishers including Dark Horse Comics, IDW Publishing, Archie Comics and Dynamite Entertainment.
Nook Comics also includes "the largest digital collection of Marvel's graphic novels" available through a third party.
Barnes & Noble launched its Nook Magazines service exclusively for its Nook Colour tablet last year, before bringing it to Android and iOS tablets. Nook Comics is expected to follow in its footsteps and land on the iPad in the future.
The bookseller released its Nook Tablet in November last year, priced at $249 (£155).
