Near-infrared fluorophores for biomedical imaging

Фотоиндуцированная деградация оптических свойств коллоидных квантовых точек Ag-=SUB=-2-=/SUB=-S и CdS, пассивированных тиогликолевой кислотой-=SUP=-*-=/SUP=-

“…Размерно-зависимые спектры оптического поглощения и люминесценции, высокий коэффициент экстинкции и эффективность люминесценции позволяют использовать КТ в таких областях, как фотовольтаика, фотокатализ, люминесцентное маркирование биологи-ческих объектов и биосенсорика и т. д. [1][2][3][4][5]. Имеются сообщения о применении коллоидных растворов для генерации второй гармоники [6][7][8].…”

Correlating 3D light to 3D electron microscopy for systems biology

“…Live LM imaging in nontransparent organisms with LM is advancing with development of biologically compatible nearinfrared probes [59], longer wavelengths more optimal for penetrating tissues [60], and photoacoustic modalities [61]. A broader set of biological systems can be studied in vitro, where larger samples can be made transparent by extracting lipids to reduce photon scattering.…”

Optical Biosensing and Bioimaging With Porous Silicon and Silicon Quantum Dots (Invited Review)

“…Usually with etching based methods, color tuning can be achieved to cover the entire visible to near infrared range [102]. The near infrared emission is particularly attractive as it allows penetration of biological tissues where scattering signals and absorption level is at minimal, a feature that is unachievable with visible emissions [107]. An emerging recent method of the top down method of preparing silicon quantum dots is fast modifications [108][109][110].…”
