摘要:
Siliceous materials were prepared by adding one or more additives, including one or more water soluble polymers, and derivatives thereof, as well as trifunctional silanes, to sols containing tetraalkoxysilanes derived from polyols. The polymers facilitate phase separation of the growing silica gel matrix, leading to high surface area self-supporting silica gels with cure occurring at ambient temperatures. The materials also show a significant reduction in shrinkage properties and significant protein stabilization abilities.
摘要:
The present invention includes polyol modified titanium compounds, their preparation and use in methods to make biomolecule compatible monolithic titania. The invention also includes the use of the biomolecule compatible monolithic titania in bioanalytic applications, for example in biosensors, chromatographic columns, microarrays and bioaffinity columns.
摘要:
The disclosure includes methods for preparing organosilicon-containing 1,2,3-triazoles by reacting an organosilicon containing azide with an alkyne compound or an organosilicon containing alkyne with an azide compound under thermal reaction conditions.
摘要:
The present disclosure relates to water-soluble stable gold nanoparticles (AuNPs) and methods for making the same. The present disclosure also includes the use of AuNPs, for example, in biological, medical and environmental assays for the detection of analytes, as well as biological and medical imaging.
摘要:
The methods and compositions of the present invention are directed to coloration of anagenic hair. The methods involve priming and deep cleaning the anagenic hair followed by coating the hair strands with a composite pigment containing film of a small molecule and a film forming composition which covalently interact to form an intimate three dimensional silicone network incorporating the pigment on the surfaces of the hair.
摘要:
A photo-responsive delivery system useful to deliver a compound to a target site is provided. The system includes a physiologically compatible matrix crosslinked with a photo-responsive matrix cross-linking agent. A method of making the delivery system and a method of delivering a compound to a target site using the system are also provided.
摘要:
The present invention relates to methods of immobilizing membrane-associated molecules within a sol-gel matrix. The membrane-associated molecule is embedded in the bilayer of a liposome. The molecule-liposome assembly remains functionally intact when it is immobilized within a protein and membrane-compatible sol-gel derived from polyol silane precursors or sodium silicate. The activity and stability of the entrapped membrane-associated molecule was significantly improved in macroporous silica.
