Dr. Malik's research activities are focused on separations chemistry.
His research group is engaged in developing advanced technology for high-performance differential migration micro separation techniques in analytical chemistry.
The ultimate goal of his research is to equip analytical chemistry with powerful separation tools for high resolution chromatographic and electrophoretic analysis and characterization of complex,
multi-component material systems of biomedical, environmental, and industrial interests.
Present emphasis is on developing:
novel column technology, new physico-chemical principles for analytical separations, effective strategies for miniaturization of separation systems, surface deactivation chemistry for small
diameter capillaries, methods for in situ creation of tailor-made surfaces and monolithic separation beds for micro columns, and advanced material systems and technologies for analytical
separations and sample preparations.
Current Research Interests
Dr. Malik's current research emphasis is on advanced technology for high-performance microseparation columns and solventless microextraction devices.
Recent research efforts involving sol-gel chemistry have resulted in the development of high-resolution open tubular and monolithic columns for capillary gas chromatography (GC),
capillary zone electrophoresis (CE), capillary electrochromatography (CEC), high-performance liquid chromatography (HPLC), and related separation techniques.
The sol-gel approach has also led to the development of thick coatings of high thermal and solvent stability for solid-phase microextraction (SPME).
Development of capillary microextraction (CME) devices with in situ created sol-gel coatings and monolithic beds, and their hyphenation with high-resolution separation techniques using
sol-gel columns are other areas of emphasis in Dr. Malik's current research program.
New Research Directions
Recently Dr. Malik has initiated a new direction in column technology research: sol-gel chemistry-based advanced column technology for micro separation techniques.
This novel approach to column technology allows for the creation of tailor-made surfaces and monolithic separation beds to achieve wide range of selectivity and solute migration characteristics.
The new technology can be effectively applied to the interior of small-diameter capillaries to in situ create surface-bonded stationary phase coatings and monolithic beds for a wide range of
analytical separation techniques including GC, HPLC, SFC, CZE, and CEC. It can also be applied to create organic-inorganic hybrid coatings on the outer surface of solid-phase microextraction
fibers for sample preparation.
Recent achievements by Dr. Malik's research group in this new area have found wide recognition both nationally and internationally, as is evidenced by the number of his invited lectures on
the subject at the national and international scientific forums on analytical separations.
One of Dr. Malik's publications titled Sol-gel Column Technology for High Resolution Gas Chromatography has made the front cover of Analytical Chemistry (Vol. 69, No. 22, pp. 4566-4576, 1997).
A scanning electron micrograph from one of Dr. Malik's publications on sol-gel monolithic column technology (Anal. Chem. 2000, 72, 4090-4099)
has made the front cover of the popular Analytical Chemistry Textbook by Daniel C. Harris (6th Edition, 2002).
