Thin biodegradable carrier bags have a property profile that is similar to compost bags ... 

Except for the optical presentation and the resulting need for printability, biodegradable carrier bags have to fulfill very similar requirements to biodegradable compost bags. 

Biodegradable drug carriers composed of biopolymers or hpid membrane vesicles (liposomes) can be used to formulate protein drugs in colloidal or suspension dosage forms. These biodegradable carriers can release incorporated protein in a controlled and sustained manner. 

Since r is constant for a non-biodegradable carrier such as PMMA, the slopes a, P, etc., should reflect changes in the diffusion coefficient D, and therefore differences in porosity, between formulations. The first-order drug release rate constants can be calculated from the slopes of the a and P phases of the release profile.

Some of the parameters influencing the tumoritropic behaviour of soluble macromolecules have now been elucidated, permitting development of more sophisticated approaches using biodegradable carriers and linkages carefully designed for selective cleavage by tumour-associated enzymes. 

It can be concluded that die use of cytokines and stimulatory molecules in conjimction with absorbable/biodegradable carriers for eliciting immuno-mediated antitumor responses is one of the most promising approaches for cancer immunotherapy. Availability of potent cytokines and signaling molecules, and advances in peptide-specific and DNA vaccines, coupled with recent developments in absorbable, solid, ionic micro- and nano-particles as well as liquid polyelectrolytes are expected to produce an exponential growth in the area of immunotherapy. This projection is in concert with ... 

Biodegradable polymeric materials have been used successfully in protein delivery. Some of the characteristics of biodegradable carriers that can be manipulated to maintain protein stability include water swelling, hydrophobicity, and chemical nature of degradation products [79],...

More recently, a series of linear PAAs with repetitive disulfide linkages in their backbone (SS-PAAs) has been developed as biodegradable carriers for gene delivery. These bioreducible SS-PAA polymers were synthesized via Michael-type polyaddition of the primary amine monomers to Nff -cystamine-bisactylamide (CBA) in equimolar monomeric ratios. These polymers have been designed to form nanocomplexes with nucleic acids, which remain relatively stable in extracellular media but are prone to fast degradation in the reductive intracellular environment due to cleavage of the... 

Newly developed responsive particles consist of a non-biological but biodegradable carrier and natural fluorophores encapsulated in the carrier. These particles would provide safety benefits. Furthermore, these particles could be designed with the appropriate density and shape of a microorganism to mimic the aerodynamic movement of a microorganism. Also, such as particle can be used as a simulant for mimicking the fluorescence properties of microorganisms.
