The optimization of graphene sensing layer against Escherichia coli
… Based on the electrical resistance, the sensing layer was able to detect E. coli against Staphylococcus aureus (S. aureus) with resistance difference 3.97 Ω and Limit of Detection (LOD) 16 CFU/mL. FE–SEM image shows the dispersion and attachment of E coli on the surface of the sensing …

Exploiting Optical Contrasts for Cervical Precancer Diagnosis via Diffuse Reflectance Spectroscopy
… Another method to enhance optical contrast is to selectively interrogate different depths in the dysplastic cervix. For instance, scattering has been shown to increase in the epithelium (increase in nuclear-to-cytoplasmic ratio) while decrease in the stroma (re-organization of the extra-cellular …
