Selective laser photocoagulation of blood vessels in a hamster skin flap model using a specific ICG formulation

Magnetic Nanoparticles and Their Applications in Medicine

“…The first class is found in massive materials or submicronic particles: the susceptibility is large, the magnetization increases massively with the magnetic field intensity, a remnant magnetization occurs after removal of the magnetic field and, above a critical temperature called the Curie temperature (Tc), the ferroor ferri-magnetic behavior disappears. The largest [18,20,[85][86][87][88][89][90][91] Micelles Based on surfactants or block copolymers <50 Drug carriers potentially thermo-, photo-or pH-sensitive [18,20,[85][86][87][88][89][90][91] Biodegradable polymeric capsules or spheres Polylactide, poly(lactic-coglycolic acid) and polyalkylcyanoacrylate 10-1000 Drug carriers potentially thermo-, photo-or pH-sensitive [18,20,[85][86][87][88][89][90][91] Inorganic Semiconductor quantum dots CdS 2-8 Fluorescent probes for optical diagnosis [2] Noble metal colloids Gold and silver 2-20 Fluorescent probes for optical diagnosis; light-guided and light-activated therapies [3] Magnetic [6][7][8][9][10][11][12][13] Magnetic nanoparticles and their applications in medicine -REVIEW iron oxide nanoparticles belong to this class (e.g., Tc = 580°C for Fe 3 O 4 ). If their size is lower than approx 10-20 nm, iron oxide nanoparticles are said to be 'superparamagnetic' and their main feature is the absence of remnant magnetization, limiting magnetic interactions within particles and, therefore, facilitating their stabi...…”

Experimental selective choriocapillaris photothrombosis using a modified indocyanine green formulation

“…Potential problems of the use of ICG in aqueous solution, such as weak photodynamic reactions, biodistribution to the neovasculature and selectivity, are mitigated when ICG is encapsulated 8 14. In dermatology, the fluence required to obtain blood vessel coagulation is 120 J/cm 2 when ICG emulsion is used, and reaches 240 J/cm 2 for aqueous ICG.…”

“…Ho and colleagues6 and Flower7 reported intraretinal accumulation of ICG; and Mordon and colleagues8 overcame leakage problems by delivering ICG in a lipid emulsion in dermatology. In addition, aggregation is a familiar phenomenon for various cyanine dyes 9 – 11.…”

Use of a new ICG‐Dye‐enhanced diode laser for percutaneous laser disc decompression

“…The treatment of ICG dye enhanced diode laser has also been used in the ®eld of surgical endoscopy [14,15], dermatology [16,17], urology [18], and ophthalmology [10,19±21]. ICG is a water-soluble tricarbocyanine dye with a peak spectral absorption of 800 to 810 nm, when dissolved in blood, plasma, or bile [22].…”
