Standardized protocols developed for the analysis of chemicals are mostly not directly applicable to ENP suspensions since they do not account for physicochemical parameters which are important for nanoparticle characterization (like size, shape, agglomeration/aggregation state, or surface area).
The use of enzymes has gained increasing attention particularly for the synthesis of injectable in situ-forming hydrogels because enzymes usually react under physiological conditions and, in contrast to many chemicals, are mostly regarded as biocompatible.
These chemicals are mostly impossible to sense, however, and so are difficult to avoid.
Household chemicals are mostly hazardous if swallowed and a curious pet can easily fall prey to some nasty chemical combinations if attracted to the product or chewing the container.
Within 5 minutes, the folate conjugate is internalized by tumor cells, and after 30 minutes, the remaining chemical is mostly cleared from the plasma.
Police detectives and chemical detectives were mostly still strangers, working in different worlds, especially in North America.
Mean values of physico-chemical parameters were mostly found to be high in the dry season as compared to the wet season.
When Adam Lowry and Eric Ryan launched Method in 2000, cleaning products were mostly chemical potions tucked into drab bottles.
As plants are a rich source of bioactive chemicals that are mostly free from harmful side effects, interest in finding natural tyrosinase inhibitors in bioactive chemicals is also increasing.
While those chemicals have been mostly banned, the stray oxygen atoms stay married to chlorine or fluorine for 50 years, unavailable to become part of new ozone molecules, thereby depleting the ozone layer and altering the natural balance.
