Although several biomedical assays have been developed to screen for antibodies against SARS-CoV-2, very few can be completed without drawing blood. We a rapid lateral flow screening tool that used saliva samples and yielded results could quantified using cell phone. This assay provided the sensitive detection of IgG SARS-CoV-2 within 10 min. started by synthesising, modifying, characterising g...

The influence of relative humidity on the consumption ethyl centralite during degradation a nitrocellulose-based propellant was investigated. For such energetic material, long term safe storage – maybe decades is required and various conditions can be found. investigations chemical integrity based accelerated ageing by heating stability tests are not sufficient to characterize in real condition...

Aptamers are oligonucleotides or peptide molecules that bind to a specific target molecule with high affinity. In particular, nucleic acid aptamers can be selected among randomized sequences using the Systematic Evolution of Ligands by Exponential enrichment (SELEX) method, in which selections of oligonucleotides that bind to the target molecule are iterated. Thus, selection of nucleic acid apt...

The incorporation into a 7% polyacrylamide gel of a nucleic acid-specific photochemical reagent 4,5',8-trimethylpsoralen at a concentration of 1 mg/dl of acrylamide solution improves both the sensitivity and the efficiency of the transfer of plasmid DNA fragments from the gel onto nitrocellulose filters. This improvement allows detection by blot hybridization of DNA fragments as small as 57 bp ...

Engraftment and healing of native or cultured skin grafts depend on adherence, vascularization, and control of microbial contamination in the wound bed. Fibrin sealant is a biocompatible polymer that may be used to promote skin engraftment by serving as a delivery vehicle for antimicrobial drugs. Human fibrin sealant (25 mg/ml) was polymerized with antibacterial agents (mupirocin [32 micrograms...
