**CERTIFICATION**





I,
      Robert
      Baron, certify that:





1)
      I have
      reviewed this quarterly report on Form 10-QSB of NanoSensors, 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 and I are responsible for establishing and
        maintaining disclosure controls and procedures (as defined in Exchange Act
        Rules
        13a-15(e) and 15d-15(e)) for the registrant and we 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 the registrant, including its consolidated
        subsidiary, is made known to us by others within those entities, particularly
        during the period in which this quarterly report is being
        prepared;





*b)
      [Paragraph omitted in accordance with SEC transition instructions contained
      in
      SEC Release 34-47986]*




c)
        Evaluated the effectiveness of the registrant's disclosure controls and
        procedures and presented in this quarterly report our conclusions about the
        effectiveness of the disclosure controls and procedures, as of the end of
        the
        period covered by this quarterly report based on such evaluation;
        and





d)
        Disclosed in this quarterly report any change in the registrant's internal
        control over financial reporting that occurred during the registrant's most
        recent fiscal quarter (the registrant's fourth fiscal quarter in the case
        of an
        annual report) that has materially affected, or is reasonably likely to
        materially affect, the registrant's internal control over financial
        reporting.





5)
        The
        registrant’s other certifying officer and I have disclosed, based on our most
        recent evaluation of internal control over financial reporting, to the
        registrant's auditors and the audit committee of the registrant'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 the registrant'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 registrant's internal control over financial
      reporting.
