Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 26, 2011, Nanophase Technologies Corporation (the "Company") was notified by the Listing Qualifications Department of the Nasdaq Stock Market ("NASDAQ") that the Company's application to transfer its listing from the NASDAQ Global Market to the NASDAQ Capital Market had been approved. The Company's shares began trading on the NASDAQ Capital Market on May 31, 2011.

Previously, the Company disclosed that on May 17, 2011, it had received a notice from NASDAQ's Listing Qualifications Department stating that, as of the most recent quarterly reporting period, the Company's reported Stockholders Equity of $9,979,845 fell below the $10,000,000 required by NASDAQ Listing Rule 5450(b)(1)(A), and the Company did not meet other available continued listing standards for the NASDAQ Global Market. The notice stated that the Company could either submit a plan for regaining compliance with the NASDAQ Global Market Listing Rules or apply to transfer its listing to the NASDAQ Capital Market. The Company decided on May 20, 2011 to apply for a transfer of listing to the NASDAQ Capital Market. That transfer was approved and implemented by NASDAQ, and disclosed via press release on June 1, 2011. The press release is attached as an exhibit to this filing.
