Synthesis and characterization of Bi2S3 composite nanoparticles with high X-ray absorption

Bi 2 S 3 -embedded mesoporous silica nanoparticles for efficient drug delivery and interstitial radiotherapy sensitization

“…More recently, it has been suggested the significant radiosensitization effect of Bi 2 S 3 nanoparticle could be successfully realized on the tumor-bearing mice model in the X-ray radiotherapy research, resulting in significantly higher inhibition effect for the tumor growth [12]. Meanwhile, as we known, the lower cost of bismuth element compared to gold could make the Bi 2 S 3 nanoparticle a better candidate to further commercial use [13,14]. Thus, it is suggested that Bi 2 S 3 nanoparticle is an ideal alternative to evaluate the therapeutic effect of nanomedicine based radiosensitizer in the interstitial radiotherapy research.…”

Facile green synthesis of bismuth sulfide radiosensitizer via biomineralization of albumin natural molecule for chemoradiation therapy aim

“…HNPs as novel important properties are attractively considered for biomedical applications. These types of biomaterials have shown abundant application in various biomedical fields, especially, as radiosensitizer [5,6]. Moreover, recent years bismuth compound nanomaterials have attracted huge attention in this field as well.…”

“…Moreover, recent years bismuth compound nanomaterials have attracted huge attention in this field as well. Bismuth is a typical high-Z element with a high X-ray attenuation coefficient (5.74 cm 2 .kg À1 at 100 keV) [6]. Obviously, the bismuth compounds have the X-ray computed tomography enhancement efficiency [7].…”

“…Obviously, the bismuth compounds have the X-ray computed tomography enhancement efficiency [7]. In addition, the possibility of bismuth nanoparticles for in vivo X-ray computed tomography imaging and photothermal therapy/radiotherapy has been demonstrated very lately [6].…”

Biomedical applications of bismuth oxide based nanocomposite: computed tomography and anticancer drug loading

“…Bismuth based nanoparticles have attracted great attention for CT imaging. Bismuth nanoparticles and bismuth oxide (Bi 2 O 3 ) [13], bismuth sulfide (Bi 2 S 3 ) [14] and bismuth selenide (Bi 2 Se 3 ) [15]forms have been investigated as a part of nanostructures which used for CT contrast enhancement. Comparing to iodine (Z=53), bismuth nanoparticles (Z=83) have advantages of higher atomic number, lower toxicity and cost [16].…”
