Exhibit 23.1

               CONSENT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

We have issued our report dated February 25, 2003 accompanying the financial
statements as of and for the year ended December 31, 2002 of Unigene
Laboratories, Inc. contained in the Registration Statement and Prospectus. Our
report contains an explanatory paragraph that states that Unigene Laboratories,
Inc has stockholder demand loans in default, has suffered recurring losses from
operations and has a working capital deficiency which raises substantial doubt
about its ability to continue as a going concern. The financial statements do
not include any adjustments that might result from the outcome of that
uncertainty. We consent to the use of the aforementioned report in the
Registration Statement and Prospectus, and to the use of our name as it appears
under the captions "Selected Financial Data" and "Experts."
