The present disclosure provides a system comprising a communication interface and computer for assigning a label to the biomolecule fingerprint, wherein the label corresponds to a biological state. The present disclosure also provides a sensor arrays for detecting biomolecules and methods of use. In some embodiments, the sensor arrays are capable of determining a disease state in a subject.

Disclosed herein are compositions comprising nanoliposomes useful for the treatment and prevention of cerebrovascular and aging-related degenerative diseases.

Cells and lipid-based structures are described herein, in particular cells and lipid-based structures comprising membrane portions derived from cells having a label covalently attached thereto, as are compositions and kits comprising such cells and structures, and methods for using the cells and structures, in particular for determining membrane coverage and/or orientation as well as for screening methods/assays, and the like.

Disclosed herein are compositions comprising nanoliposomes useful for the treatment and prevention of cerebrovascular and aging-related degenerative diseases.

Provided herein is a method of functionalizing a particle, as well as methods of optically tracking a particle, isolating enveloped viral particles from a sample, quantifying enveloped virus particles in a sample and assessing enveloped viral aggregation in a sample. Kits are also provided. The particle is typically a viral particle.
