Chitosan-capped gold nanoparticles (CS-AuNPs) were synthesized via a rapid method by exposing 0.75 mL of 10 mM HAuCl4 and 5 mL of 0.1% w/v chitosan solution to microwave irradiation at 125 °C for 40 s. The resulting red ...

A smartphone-based technique for determining the titration equivalence point from a linear-segment curve was developed for the first time. In this method, a titrant in an increasing microliter-volume was added to a set of ...

In many pharmacopoeias, the limit test used for determining the level of aluminum in citric acid labeled for use in the manufacture of dialysate, is based on solvent extraction using 8-hydroxyquinoline and measurement of ...

Since microwave (MW)-assisted synthesis of gold nanoparticles (AuNPs) using Caesalpinia sappan (CS) extract as both a reducing and stabilizing agent is currently unavailable, a MW-based synthesis protocol was investigated ...

Ion pair extraction coupled with digital image colorimetry has been developed as a promising platform for pharmaceutical analysis. The applicability of the approach was demonstrated through the assay of chlorpromazine ...

A new, smartphone-based colourimetric method for the assay of d-penicillamine formulations relying on the Ellman’s reaction was developed by performing the colourimetric reaction in a microplate. Subsequently, the plate ...

Objectives: The aim of this work was to enable students to set up and organize for themselves online review activities after class. Materials and Methods: Students worked as groups to create short notes and quizzes that ...

While glutaraldehyde is a commonly used cross-linker for enzyme immobilization, it is unsafe and requires the multi-step cross-linking procedure. Here, we report a facile, fast and cost-effective fabrication of immobilized ...

Cellulose acetate nanofibers with different degrees of alignment (randomly aligned (RA), partially aligned (PA), and highly aligned (HA)) were produced using an electrospinning technique. The different degrees of alignment ...
