C-dots have been considered as possible replacements for organic dyes and metallic quantum in bioimaging
due to their chemical stability, broad excitation ranges, and excellent fluorescence properties.

ZnO NPs exhibit efficient blue emissions and near-UV emissions, which have green or yellow luminescence related to oxygen vacancies, therefore further extending its application into bioimaging

The luminescent property also makes porous silicon an attractive biomaterial in bioimaging
. Luminescent porous silicon nanoparticles with emission on 650-900 nm range, fabricated by lifting off porous silicon film and sonication, are suitable candidates for in vivo imaging , as like silicon quantum dots, they can be easily degraded in aqueous solutions into non-toxic orthosilicic acid.
The amplified product (905 bp) was electrophoresed in 2% agarose gel stained with ethidium bromide (0.5 [micro]g/ml) and image was documented by gel documentation system (Mini BiS Bioimaging
However, a facile and "green" mild process using aqueous medium for the preparation of AgIn[S.sub.2]/polymer nanoconjugates with high luminescent properties (i.e., PL quantum yield, QY > 40%) for augmenting bioimaging
sensitivity is beyond the scope of the current study and remains a challenge for the future researches.
Triplet-triplet annihilation has been already applied with success in several research fields, as in luminescence bioimaging
, photovoltaics [34, 35], and photoinduced drug release .
modalities in evaluation of an experimental osteonecrosis induced by a combination of lipopolysaccharide and methylprednisolone.
The results showed that the GQDs could be a promising candidate for bioimaging
. Most importantly, compared to the traditional quantum dots (QDs), the GQDs is chemically inert.

They also speculate on future research and discuss potential developments for their use in sensors, bioimaging
, and energy harvesting and conversion.
