It is electron dense marker and has a wide application in electron
microscopy, light microscopy, blotting procedures. Recently conjugates of
antibodies with colloidal gold
were applied for quantitative photometric determination of appropriate
antigens. Colloidal gold conjugated with antibodies are applied widely
also for qualitative determination of appropriate antigens in strips.
Recently new ways for application of colloidal gold also were presented.
Modified colloidal gold is able to bind DNA and to detect hybridization.
Colloidal gold for various purposes is prepared with various sizes. We can
supply the following sizes 3-5 nm, 13-15 nm, and 20 nm, 40 nm 50 nm that
can be used in various research areas. Concentration: approximately 0.01%
A520 =approximately 0.75.

These nanoparticles have unique optical properties. They have two bands
of plasmon resonance. One of them is about
400 nm but other is tunable and can be in range from 580-680 nm. This band
is sensitive to any border effect and such nanoparticles can be very
useful
in various biosensors.

Quantum dots (QDs) are inorganic semiconductor nanocrystals that have
tunable fluorescence properties. QDs have high quantum yields, broad
absorption spectra, narrow size-tunable emissions, and are resistant to
photobleaching as well as to chemical degradation. Quantum dots (QDs) have
the potential to become a new class of fluorescent probes for many
biological and biomedical applications. Our quantum dots are water soluble
and they can be applied directly for conjugation of biomolecules
