Dr Pushpamalar is interested in the fabrication of natural biodegradable polymers into an useful materials that have potential use in many areas in industries. The only reason for looking into formulating biodegradable biomaterial is that it could disintegrate into smaller fragments that are non-toxic remnant after use.  She is experienced in producing carboxymethylcellulose (CMC) from sago waste and with incorporating other polysaccharides to prepare hydrogels in forms of beads, disks, microcapsules, and membranes  with different properties using various crosslinking methods. It can act as a carrier for active ingredients. It can be used in control release of drug delivery in medical area and slow release of fertilizer in agriculture. These polymer carriers are also could be utilized to improve wastewater treatment and solid waste management. Different methods could be used to combine different polymers to produce biodegradable plastics and nanotubes. Silver nanoparticles syntheses from various methods using plant sources are being explored.

Research Interests

Research interest is in developing new biodegradable polymers using plant waste and currently focusing on preparing cross-linked CMC hydrogel to be used as control release device for anticancer drug and slow release device for application of fertilizer. CMC and other polysaccharides are also incorporated to prepare drug delivery vehicles and loaded with drugs via physical or chemical methods. There are other active ingredients such as flavors, fertilizers, pesticides, herbicides and natural supplements can be loaded to the polymeric material and study the release pattern. Carboxymethyl cellulose and chitosan also used to prepare halloysite nanotubes for application in electronic packaging and automotive industry. Incorporate two different polysaccharides with different properties and prepare desired biodegradable plastics by blending, grafting and other methods. And also research is being done on carboxymethyl cellulose cross-linked with chitosan to prepare hydrogel beads for encapsulating activated sludge from wastewater treatment plant to degrade p-nitrophenol. Silver nanoparticles are prepared from various methods including using plant sources, CMC and cellulose. These silver nanoparticles are incorporated to polysaccharides to form hydrogel and used for wound dressing.

Currently, looking into preparing the biodegradable biomaterials as scaffold for tissue engineering, skin tissue grafting, electroactive cues for neural tissues. This natural polymer containing biomaterial tend to biocompatible with body and reduces or eliminates the toxicity issue that arises when using a synthetic materials.
