which involves the use of photosensitizer (PS),2 light,3 and endogenous molecular oxygen4 to kill cancer cells or microbes. Individually, each component is nontoxic, but when PS is irradiated with light, the photochemical reactions result in the formation of highly reactive singlet oxygen species that are responsible for cytotoxicity and cell death
. One of the key factors to determine the therapeutic function is the efficiency of photosensitizers (PSs)
With high charge density in the polymer chain, the azonia-containing polyelectrolytes may show affinity to negative charge species (such as bacteria membrane and DNA), which enables them to wrap the surface of bacteria and physically kill them.
The azonia rings are highly electron-deficient, and it is thus easy to form donor–acceptor (D–A) structures with tunable emission color by combining with different electron donors.
Polyelectrolytes have demonstrated great potency in many aspects, for example, thickening agents in food industry, wastewater treatment in environment science, and diagnostic and therapeutic agents in medicine.
3买并不代表一定会创新高什么的,小级别买卖点的意义在大级别走势的意义彰显的时候才得以彰显。 所以不创新高出个2卖也是很正常的事情
平常我們一天到晚忙這個我,原來這個是什麼 ─壞聚,真正騙你的根本就在這裡啊!
而這個東西在無常的變壞當中,它是虛假的,是一無可取的,結果因為我們「染慧」 ─染污的認識,慧是一種觀照的力量,這個觀照的力量透過了染污、雜染了,你看不清楚,看錯了,以為在這個上頭有一個我或者我所。
In some chromophores the absence of a bridge (D-A+) between the donor and acceptor fragments enhances the NLO properties and the single crystal structure of such a material has been determined by X-ray diffraction.
