EXHIBIT 31.1
                                  ------------

I, Manfred F. Dyck, certify that:

1.    I have reviewed this quarterly report on Form 10-QSB of Hydromer, Inc.;

2.    Based on my knowledge, this quarterly report does not contain any untrue
      statement of a material fact or omit to state a material fact necessary to
      make the statements made, in light of the circumstances under which such
      statements were made, not misleading with respect to the period covered by
      this quarterly report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this quarterly report, fairly present in all
      material respects the financial condition, results of operations and cash
      flows of the registrant as of, and for, the periods presented in this
      quarterly report;

4.    The registrant's other certifying officer, Mr. Robert Y. Lee and I am
      responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the
      registrant and have:

      a)    designed such disclosure controls and procedures to ensure that
            material information relating to the registrant, including its
            consolidated subsidiaries, is made known to us by others within
            those entities, particularly during the period in which this
            quarterly report is being prepared;

      b)    evaluated the effectiveness of the registrant's disclosure controls
            and procedures as of a date within 90 days prior to the filing date
            of this quarterly report (the "Evaluation Date"); and

      c)    presented in this quarterly report our conclusions about the
            effectiveness of the disclosure controls and procedures based on our
            evaluation as of the Evaluation Date;

5.    The registrant's other certifying officer, Mr. Robert Y. Lee and I have
      disclosed, based on our most recent evaluation, to the registrant's
      auditors and the audit committee of registrant's board of directors (or
      persons performing the equivalent functions):

      a)    all significant deficiencies in the design or operation of internal
            controls which could adversely affect the registrant's ability to
            record, process, summarize and report financial data and have
            identified for the registrant's auditors any material weaknesses in
            internal controls; and

      b)    any fraud, whether or not material, that involves management or
            other employees who have a significant role in the registrant's
            internal controls; and

6.    The registrant's other certifying officer, Mr. Robert Y. Lee and I have
      indicated in this quarterly report whether there were significant changes
      in internal controls or in other factors that could significantly affect
      internal controls subsequent to the date of our most recent evaluation,
      including any corrective actions with regard to significant deficiencies
      and material weaknesses.
