Better biosensor technology, as described by the study team, “may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders,” they claim. The research, which uses a graphene and gold-based platform and sophisticated imaging equipment, tracks the growth of stem cells by spotting the genetic material (RNA) necessary for converting them into brain cells. (neurons).
Numerous cell kinds can be developed from stem cells. Because diseased cells in neurological disorders like Alzheimer’s, Parkinson’s, stroke, and spinal cord injury need to be replaced or repaired, stem cell therapy holds potential as a regenerative treatment. But before stem cells can be used in treatments, characterizing them and deciding on their destiny must be worked out. Tumor growth and unchecked stem cell change continue to be major obstacles.
Assuring high sensitivity and accuracy in detecting biomarkers—indicators like altered genes or proteins—within the intricate stem cell microenvironment is crucial. The use of biosensor technology to study various stem cell relationships has shown much promise. The team’s innovative biosensing device comprises various ultrathin graphene layers and gold nanostructures.
The platform detects genes and characterizes various types of stem cells with higher accuracy, selectivity, and sensitivity than current biosensors when used with high-tech imaging (Raman spectroscopy). The group is confident that various applications can profit from the technology.
