• SBSE offers advantages in terms of efficiency and reduced solvent consumption.

Purpose of the Study:

• To review the theoretical aspects of SBSE.
• To highlight recent applications of SBSE in pharmaceutical, biomedical, environmental, and food analysis.
• To discuss new developments in SBSE coatings and sorbent phases.

Main Methods:

• Review of existing literature on SBSE.
• Discussion of factors influencing extraction efficiency (e.g., time, pH, temperature, agitation).
• Overview of optimization strategies for SBSE.

Main Results:

• SBSE has demonstrated significant advantages over traditional extraction techniques.
• Numerous applications exist across diverse analytical fields.
• Recent developments focus on novel instrumental approaches and sorbent phases beyond PDMS.

Conclusions:

• SBSE is a versatile and effective extraction technique.
• Continued development of new sorbent phases is crucial for expanding SBSE applications.
• Advancements in instrumental approaches further enhance SBSE capabilities.
