Provided herein are nanobubbles designed for use in ultrasound-mediated ablation of cancer cells. The nanobubbles undergo ultrasound-mediated cavitation at an ablation threshold which is significantly decreased, relative to standard ultrasound- mediated treatment of cancer cells. In exemplary embodiments, the nanobubbles comprise an amphiphilic ABC triblock copolymer, wherein block A comprises a hydrophilic polymer, block B comprises a crosslinking polymer, and block C comprises a hydrophobic copolymer comprising (i) methyl methacrylate (MMA) and (ii) a fluorinated monomer, wherein the fluorinated monomer is present in the hydrophobic copolymer of block C at 25 mole percent or less. Related treatment and diagnostic methods, as well as materials relating to the nanobubbles are provided herein. Methods of making a random copolymer are furthermore provided herein.

The synthesis of anthracene end-capped poly(methyl methacrylate)s via atom transfer radicalpolymerization (ATRP) and the kinetic analyses thereof are reported. Methyl methacrylate was polymerized in toluene at 90 °C (or 60 °C) via ATRP using 9-anthracenemethyl-2-bromoisobutyrate as the initiator and CuBr/N-(n-hexyl)pyridylmethanimine as the catalyst. Anthracene end-capped polymers with predetermined
报道了通过原子转移自由基聚合(ATRP)合成蒽端基封端的聚(甲基丙烯酸甲酯)及其动力学分析。甲基丙烯酸甲酯在90°C(或60°C)下通过ATRP在甲苯中聚合,使用9-蒽甲基-2-溴异丁酸酯作为引发剂,并使用CuBr / N-(n-正己基)吡啶基甲亚胺作为催化剂。获得了具有预定分子量和低多分散性(PDI <1.3)的蒽封端聚合物,其特征为11 H NMR和UV-可见。引发剂和Cu(I)的浓度,最初添加的Cu(II)的浓度以及ATRP系统的反应温度对反应动力学具有决定性的影响。当引发剂和Cu(I)的浓度或反应温度相对较高,或者初始添加的Cu(II)浓度相对较低,因此系统中的自由基浓度相对较高时,聚合动力学符合Fischer方程(ln([M] 0 / [M])∝ t 2/3)。另一方面,Matyjaszewski方程(ln([M] 0 / [M])∝ t当引发剂和Cu(I)的浓度或反应温度太低或
