      SpectraScience, Inc. and have:





(a)
      Designed such disclosure controls and procedures, or caused such disclosure
      controls and procedures to be designed under our supervision, to ensure that
      material information relating to SpectraScience, Inc., including its
      consolidated subsidiaries, is made known to us by others within those entities,
      particularly during the period in which this report is being
      prepared;


(b)
      Designed such internal control over financial reporting, or caused such internal
      control over financial reporting to be designed under our supervision, to
      provide reasonable assurance regarding the reliability of financial reporting
      and the preparation of financial statements for external purposes in accordance
      with generally accepted accounting principles;


(c)
      Evaluated the effectiveness of SpectraScience’s disclosure controls and

      affect, the Company’s internal control over financial reporting;
      and





5.
 
      The Company’s other certifying officer and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the Company’s
      auditors and the audit committee of the Company’s board of directors (or persons
      performing the equivalent functions):





(a)
        All significant deficiencies and material weaknesses in the design or
      operation of internal control over financial reporting which are reasonably
      likely to adversely affect SpectraScience’s ability to record, process,
      summarize and report financial information; and


(b)
        Any fraud, whether or not material, that involves management or other
      employees who have a significant role in the small business issuer’s internal
      control over financial reporting.
