Low-cost automation of gram's microbiology staining procedure
Gram stain is a differential stain which distinguishes bacteria into 2 large groups;rnGram-negative and Gram-positive. Similar to other staining methods, Gram stain isrnpurposed to make the morphology and arrangement of cells more visible duringrninvestigation. Moreover, the differentiation ability of Gram stain makes it the mostrnessential and valuable microbiological staining procedure available. However, thernprocedure of Gram stain involves waiting phases and takes reasonable time. The mainrnobjective of this thesis is to design and construct a low-cost automatic apparatus tornperform Gram staining. This thesis is significant while most hospitals in Indonesia arernstill performing Gram stain manually and thus, it is not time-, cost- and labor-rnefficient. Optimistically, the proposed thesis device would increase laboratoryrnefficiency while cutting the cost, as well as raising patients throughput and in turn,rnprofit.
