Chronic wound infection is a serious healthcare issue across the globe. Herein, the nanocomposite hydrogels comprising cuprous oxide nanoparticles grafted sepiolite (Cu2O/Sep) and poly(vinyl alcohol) (PVA) were prepared via the freeze-thaw method. The physical, structural, mechanical, and antibacterial properties of the nanocomposite hydrogels were...
The contamination of natural water bodies with bacteria and hexavalent chromium [Cr (VI)] is a global issue. In this study, cuprous oxide (Cu2O) and silver oxide (Ag2O) nanoparticles were separately immobilized on the pristine sepiolite (Sep) to develop Cu2[email protected] and Ag2[email protected], respectively. Transmission electron micrographs o...
Titanium dioxide (TiO 2) nanoparticles (NPs) are one of the topmost widely used metallic oxide nanoparticles. Whether present in naked form or doped with metals or polymers, TiO 2 NPs perform immensely important functions. However, the alteration in size and shape by doping results in improving the physical, chemical, and biological behaviour of Ti...
Capping agents are of utmost importance as stabilizers that inhibit the over-growth of nanoparticles and prevent their aggregation/coagulation in colloidal synthesis. The capping ligands stabilize the interface where nanoparticles interact with their medium of preparation. Specific structural features of nanoparticles are attributed to capping on t...
Incorporation of nanoparticles into a number of manufacturing products raised the concern of environmental release via deliberate or accidental routes. Here, experiments were performed to examine the effect of copper oxide nanoparticles (CuO NPs), and polyvinyl pyrrolidone (PVP) and polyethylene glycol (PEG) impregnated CuO NPs on seed germination...
Role of vitamin D receptor (VDR) has been well-known in variety of metabolic disorders and in regulation of inflammation. One of the candidate gene of rheumatoid arthritis (RA) is VDR. The intention of this study was to determine the association of VDR polymorphism rs1544410 with RA in Pakistani patients. A total of 200 subjects were recruited in t...
O papel do receptor da vitamina D (VDR) já é bastante conhecido em uma série de transtornos metabólicos e na regulação da inflamação. Um dos genes candidatos na artrite reumatoide (AR) é o VDR. O objetivo deste estudo foi determinar a associação do polimorfismo rs1544410 do VDR com AR em pacientes paquistaneses. Foram incluídos no estudo 200 indiví...

Hello everyone!
It has been reported in literature that chitosan has antibacterial properties. I have chitosan available of low and medium molecular weight and I checked their antibacterial activity but there wasn't any. Can you please advice/suggest on this ?
I have performed the adsorption studies and applied Langmuir model to the data. I obtained KL value from it. In literature it is given higher the KL value stronger the interaction between adsorbent and adsorbate. But there isn't any specific value of KL given.
In literature FTIR and XRD are also performed to predict the adsorption mechanism. I have done that as well and there is shift and change in the peak intensities.
Which one is better to predict the adsorption mechanism? Either from KL value or FTIR/XRD?
I got comment on my FTIR data figure from a reviewer. The reviewer said "FTIR data in Figure should be repeated. there is no bassline." I made Y off set comparison graph of FTIR on OriginLab. Can someone guide me about the baseline of FTIR?
Thank you
Hello,
I want to load Remedesivir (RNA polymerase inhibitor) into mesoporous nanoparticles (MSNs). The issue is drug is temperature and pH sensitive and it degrades quickly. I need advice on its loading.
1- Should it be loaded to at the last step of MSN synthesis. Problem with this MSNs are extracted later on through reflux and 60 degree temperature is required. It degrades drug.
2- Should it be loaded after extraction making an ice bath but how long it should be kept on stirring?
3- Later I want to coat it with chitosan MSN loaded Remedesivir and then coating with chitosan. I am concerned about leaching and degradation of drug. Should i load drug first and then add drug?
Thank you for your suggestions.
Hello
I have prepared metal nanoparticles and did zeta potential. Normally there is a single peak in sample but now there are 3 peaks.
I prepared sample for analysis first I prepared 10 mg/mL stock solution, sonicated sample then prepared 1 mg/mL dilution from stock sonicated again. Then I filtered sample and sent for the analysis.
What should I do so I get a single peak?
Hi
I am trying to revive Pseudomonas aeruginosa from frozen glycerol stock and also from cryobeads. But there was no bacterial growth. I used nutrient agar, tryptone soy agar to streak on. Also I added glycerol stock to nutrient broth and tryptone soy broth but there was no growth.
I would appreciate your guidance.
Thank you
Hi
I am making FTIR graphs in percent transmittance. I observed the change in broadness and dip of the peak. So when dip increases does that mean there is a decline in the intensity of band? Especially in 3600-3200 cm-1 region which usually corresponds to OH groups.
Hello!
I have already published an article and given all the details of protocols in the publication. Now I am working on another manuscript but basic protocols are same and already reported. How can I report those protocols in the new manuscript without being plagiarized? Should it be given in supplementary?
