Diabetes Mellitus, Type 1
Conditions
Brief summary
The aim of the study is to analyse the biomechanical stiffness of red blood cells extracted from subjects with type I diabetes with and without microvascular complications through a biophysical characterization of red blood cells using microscopy, spectroscopy and scattering measurements. 48 subjects with type 1 diabetes, 24 with and 24 without microvascular complications will be enrolled. From all subjects a single blood sample will be taken to perform the analysis of red blood cells morpho-mechanical properties.
Interventions
A single blood test to be analysed through atomic force microscopy in the force spectroscopy mode

| Measure | Time frame | Description |
|---|---|---|
| In 48 subjects with type 1 diabetes with and without microvascular complications, the average stiffness of red blood cells, measured using atomic force microscope and quantified using Young's modulus, will be measured. | 1 day | Young's modulus values are obtained using atomic force microscopy |
