Some embodiments are directed to a system and method monitoring oxygenation in biological tissue, comprising a control unit configured and operable to receive data indicative of light response from a region of the biological tissue being subjected to illumination and/or collection at two separate wavelengths in two selected wavelength ranges and processing the data by comparing data indicative of each selected wavelength range to determine an oxygenated/deoxygenated status of the biological tissue. The two wavelength ranges include a first wavelength range in which the absorbance of the deoxyhemoglobin within the tissue is higher than the oxyhemoglobin, and a second wavelength range in which the absorbance of the oxyhemoglobin within the tissue is higher than the deoxyhemoglobin or vice versa. The two wavelengths in the two wavelength ranges include first and second wavelengths satisfying a predetermined condition of a ratio between the absorbance of the deoxyhemoglobin and oxyhemoglobin for each wavelength.

Disclosed are methods and devices useful for imaging blood-containing tissue, for example for angiography, especially retinal angiography, whereby an image is generated by dividing pixels of an image acquired at some wavelength range by corresponding pixels of an image acquired at a different wavelength range. In some embodiments, a first wavelength range includes predominantly light having wavelengths between about 400 nm and about 620 nm and a second wavelength range includes predominantly light having wavelengths between about 620 nm and about 800 nm.

The present invention provides nanoparticle conjugates incorporating the self-assembling module diphenylalanine (FF) dipeptide into a bioactive moiety. The conjugate self-assembles to form distinct nanometric structures such as nanospheres. The present invention further provides nanoparticles formed by supramolecular co-assembly of the conjugates with a diphenylalanine (FF) dipeptide or analog thereof, to generate bioactive self-assembled nanostructures.
