Figure Lengend Snippet: Data were normalized and the scale is indicated below the figures. ( a ) Unsupervised hierarchical clustering was performed for individual technical replicates. ( b ) Competitive inhibition of EV interactions with lectin microarray with mannose (Man) and N -acetylglucosamine (GlcNAc). ( c ) Lectin microarray of PNGase F-treated EVs. Significance (* = p ≤ 0.05) was determined by the ANOVA test.

Article Snippet: Probes (neoglyconjugates, glycoproteins and lectins) were printed on Nexterion® Slide H (Schott, Mainz, Germany) using a SciFlexArrayer S3 piezoelectric microarray printer (Scienion, Berlin, Germany) under constant 62% (+/−2%) humidity at 20 °C essentially as previously described .

Figure Lengend Snippet: Schematic representation of steps followed in manufacturing and analyzing microarrays, including drug and polymer solutions preparation, pipetting into well-plate, withdrawing drug solution through the printer nozzle and then dispensing at the required amount in the desired prelocated place on the substrate followed by repeating the same process for the polymer solution to print it onto the printed drug solution droplets.

Article Snippet: A miniaturized, high-throughput technique was used to print microarrays of the drug–polymer mixtures using a piezoelectric inkjet printer Sciflexarrayer S5, Scienion (inkjet printer software sciflexarrayer (Scienion A, version 2.09.002)), and 70 μm orifice nozzle type 2 coating (Scienion, Germany).

Figure Lengend Snippet: Examples of different APIs/PVPVA printed dispersions. All images are reported without a cross-polarized filter (top part of each section) and with a cross-polarized filter (bottom part). The images were arranged in ascending order according to the displayed drug–polymer ratio. The top section shows the API/polymer loading ratios with no birefringence (no crystallization monitored). In contrast, the middle section shows the API/polymer loading ratios that show the start of birefringence detection (start of crystallization), and the bottom section shows the API/polymer loading ratios that show apparent birefringence detection (crystallization). Three different ratios for API/polymer loading were displayed to compare the assessment of crystallization by POM. All images are reported after storage of the microarrays in accelerated conditions for 6 months (75% relative humidity and 40 °C in stability oven). Final mass: 1000–1100 ng.
