Recent trends in sample preparation strategies employed in efficient Bio-analytical methods -An overview

The most recent developments in sample preparation techniques for bioanalysis are examined in this article, offering a synopsis of the theory, potential applications, and automation, along with a comparative analysis of the advantages and disadvantages of each approach. Nowadays, the conventional methods of protein precipitation (PP), liquid-liquid extraction (LLE), and solid-phase extraction (SPE) are thought to be archaic. In the past ten years, new methods for bioanalysis sample preparation have advanced quickly. There has been discussion of advancements in for all separation procedure. SPE technology provides distinct benefits over bioanalytical methods and a range of extraction phases. Selective sorbents and the general SPE strategy, such as hybrid SPE, molecularly imprinted polymer SPE, and solid-phase micro-extraction, including its various Dispersive solid-phase extraction, pipette extraction, and packed-sorbent micro-extraction methods. Bioanalytical techniques in PPT included the use of PPT filter plates, 96well PPT plates, and hybrid SPE PPT plate techniques. For LLE, the methods used include Liquid-Liquid Micro Extraction (LPME) and Dispersive Liquid-Liquid Microextraction (DLLME). In bioanalytical applications, online SPE employing column-switching techniques is quickly gaining traction.  Hollow fiber-based LPME possibly offers a wide range of potential applications in the field of drug analysis, since it can offer high drug enrichment and good sample clean-up. There are several benefits to using PP filter plates and tubes for sample preparation, including the elimination of proteins and phospholipids from plasma and serum.
