Vivek smiled, logging his results. Through the simple magic of chemistry and color, he had turned the invisible into the understood.
The world beneath the glass exploded into color. Amidst the sea of deep (the Gram-Positive titans), there were now bright pink specks (the Gram-Negative rebels). The mystery was gone; the identity of the colony was clear. Vivek smiled, logging his results
First, he flooded the slide with . The bacteria soaked it up, turning a deep, royal purple. “Phase one,” he whispered. “The Primary Stain.” At this stage, every microbe on the slide looked identical, cloaked in violet armor. Amidst the sea of deep (the Gram-Positive titans),
Next came the . This was the "mordant," the chemical glue. It bound to the crystal violet inside the cell walls, creating large complexes that wouldn't easily leave. The bacteria soaked it up, turning a deep, royal purple
“Now,” Vivek said, picking up the final vial, “we reveal the hidden ones.”
He reached for the four sacred vials of the technique.
