Workstation for Automated Nanomaterial Discovery and Analysis (WANDA)
WANDA is an automated robot for the synthesis of colloidal inorganic nanomaterials. WANDA features two liquid handling robot arms with heated and non-heated needles for dispensing and aspirating 10 µL-5 mL volumes into 200 µL – 40 mL reaction vials at rates of 20-1500 µL/s. Microplates with 6-96 vials can be heated and stirred in parallel from 30-120 °C in six on-deck microplate bays. 6-20 mL reactions in disposable glass vials can be heated at 30-325 °C and stirred independently with high precision in WANDA's 8-reactor LTMR array with temperature ramp rates up to 40 °C/min. Aliquots can be sampled from reactions with 40 s duty cycles. Vials can be transported across the deck using the vial gripper tool and weighed in WANDA's automated balance (0.00001 g precision). The entire system is enclosed in a nitrogen-filled glove box for air-free reactions. The glove box also includes a module for the manual preparation of precursors and a microplate-compatible centrifuge for manual and semi-automated purification of nanocrystals. Microplates of samples generated by WANDA can be characterized using the Biotek UV/Vis abs./PL plate reader, the NIRVANA NIR/Vis absorption plate reader, the Fluorolog Micromax PL and upconversion luminescence plate reader, the Bruker X-ray diffractometer, and the Horiba LabRAM Raman microscope.
