Application


  • Polystyrene adsorbents: This study highlights the use of N-lauryl sarcosine sodium salt for the extraction of functionally active recombinant proteins from inclusion bodies (SK Palanirajan, P Govindasamy, SN Gummadi - Scientific Reports, 2020).

  • Modified magnetite nanoparticles for selective trace determination: Discusses the preparation of N-Lauryl sarcosine sodium salt modified magnetite nanoparticles as an extractant for selective trace determination (H Eskandari, H Ashrafi - 2014).

  • On-plate spot test for identification and separation of surfactants: Mentions the use of N-lauryl sarcosine sodium salt in the formulation of spot tests for various surfactants (A Mohammad, A Siddiq, R Mobin, E Gaber - Journal of Industrial and …, 2014).

  • Influence of HSA on micellization: This paper explores the influence of human serum albumin on the micellization properties of N-lauryl sarcosine sodium salt and other surfactants (I Fatma, V Sharma, NA Malik, H Assad… - Journal of Molecular …, 2022).

  • Ultrasonic synthesis of stable oil filled microcapsules: This study explores the ultrasonic synthesis of oil-filled microcapsules using thiolated chitosan, potentially involving derivatives like ᴅʟ-N-Acetylhomocysteine thiolactone for improved stability and functional properties. The research provides insights into advanced microencapsulation techniques relevant in pharmaceutical and industrial applications (Link to the study).
