Modified Natural Rubber as a Simple Chemical Sensor with Smartphone Detection for Formaldehyde Content in a Seafood Sample.

A new biodegradable platform-based sensor for formaldehyde assay is proposed. Natural rubber latex was modified to polylactic acid-chloroacetated natural rubber polymer blend sheets. The polymer blend sheet was grafted using a water-based system with amine monomers as a platform, with a spot exhibiting positive polarity for immobilizing with anionic dye (Acid Red 27).

Biocompatibility and biodegradability of filler encapsulated chloroacetated natural rubber/polyvinyl alcohol nanofiber for wound dressing.

The novel biodegradable films of chloroacetated natural rubber/polyvinyl alcohol (CNR/PVA) (55/45 wt%) non-woven nanofiber films encapsulated with kaolin and starch (2.5 and 5 wt%) were produced successfully by green electrospinning technique. The effect of fillers with different content on the physical, chemical, mechanical, biocompatibility and biodegradation properties of CNR/PVA nanofiber films were investigated.
