NAICS Code is 334413 - Semiconductor and Related Device Manufacturing, with a Size Standard of 1250 Employees. NIST anticipates negotiating and awarding a firm-fixed-price purchase order to Mosaic Microsystems for this requirement. **JUSTIFICATION FOR OTHER THAN FULL AN OPEN COMPETITION:** Market research resulted in Mosaic Microsystems LLC being the only vendor to align and hermetically seal microwave coplanar waveguides into all-glass microfluidic channels. Mosaic Microsystems was the only company to fulfill the technical specifications laid out in that procurement and developed a specialized wafer alignment process to meet the needs of the procurement. No other manufacturers are known to produce the proprietary wafer bonding technology to create the hermetic seals at low enough temperatures and pressures to avoid deforming the embedded microwave circuitry. Interested parties that can demonstrate they could satisfy the requirement listed above for NIST must clearly and unambiguously identify their capability to do so in writing on or before the response date for this notice. This notice of intent is not a solicitation. Information submitted in response to this notice will be used solely to determine whether competitive procedures could be used for this acquisition. If competitive procedures are not used, it is estimated that an award will be issued 4th Quarter FY24. Any questions regarding this notice must be submitted in writing via email to clifford.nicholson@nist.gov. All responses to this notice of intent must be submitted to clifford.nicholson@nist.gov no later than 6/29/2024 at 10:00 a.m. MDT. ## Award on USAspending - Recipient: Mosaic Microsystems LLC (UEI JPLDLBVEEUP2) - Contract: 1333ND24PNB670472, purchase order - Obligated: $65,693.00 - Competition: Not Competed Under SAP, 1 offers received - Link: solicitation number NB6720102402085 equals the FPDS solicitation identifier; same awarding office 1333ND (high confidence) - Record: https://www.usaspending.gov/award/CONT_AWD_1333ND24PNB670472_1341_-NONE-_-NONE-/ ## Publications - June 17, 2024: Sources sought, due June 22, 2024 at 4:00 PM EDT.
